mistake or mislead could be happened during designing the structures because of not
knowing the proper procedure depending on the situation. Design book based on
manual or hand design is sometimes time consuming and could not be good aids with
softwares as several steps are shorten during finite element modeling. This book may
work as a general learning hand book which bridges the software and the manual
design properly. The writers of this book used linear static analysis under BNBC and
ACI code to generate a six story residential building which could withstand wind load
of 210 kmph and seismic event of that region. The building is assumed to be designed
in Dhaka, Bangladesh under RAJUK rules to get legality of that concern organization.

building and explained with references how to consider during design so that
creativity of readers could not be threated. Chapter 8 is dedicated for estimation. As a
whole the book will help the readers to experience a building construction related all
facts and how to progress in design. Although the volume I is limited to linear static
analysis, upcoming volume will eventually consider dynamic facts to perform
dynamic analysis. Implemented equations are organized in the appendix section for
easy memorizing.
BNBC and other codes are improving and expending day by day, by covering new
and improved information as civil engineering is a vast field to continue the research.
Before designing something or taking decision judge the contemporary codes and
choose data, equations, factors and coefficient from the updated one.

Design & Analysis of High rise Building With & Without Floating Column Using ...IJSRD
At present buildings with floating column is a typical feature in the modern multistory construction in urban India. There are many projects in which floating columns are adopted, especially above the ground floor, where transfer girders are employed, so that more open space is available in the ground floor. As the load path in the floating columns is not continuous, they are more vulnerable to the seismic activity. Sometimes, to meet the requirements these type of aspects cannot be avoided though these are not found to be of safe. Hence, an attempt is taken to study the behavior of a G+15 multi storey building in which some storey’s are considered for commercial purpose and remaining storey’s are for residential purpose. This paper studies the comparison & seismic analysis of the multistory buildings with floating column and without floating column. Finally, analysis & results in the high rise building such as storey drifts, storey displacement, and Base shear were shown in this study. Design and Analysis was carried out by using Extended Three Dimensional Analysis of Building Systems (ETABS) Software.

Effect of wind Load On High Rise BuildingVikas Patre
Wind load is an important design consideration for high-rise buildings due to the increasing wind forces experienced at greater heights. This document discusses wind load calculation and analysis for a 20.5m high building according to Indian code IS 875-Part 3. Static analysis of the building model in SAP2000 showed that wind load causes higher bending moments and shear forces compared to analysis without wind load. The wind pressure varies with height and building designers must account for this gradient in load to safely structure high-rise buildings.
A study on seismic performance of high rise irregular rc framed buildingseSAT Journals
Abstract Earthquakes are known as one of the most unpredictable and devastating of all natural disasters, however the unpredictable nature of occurrence of these earthquakes makes it difficult to prevent loss of human lives and destruction of properties, if the structures are not designed to resist such earthquake forces. In this paper attempt has been made to study two types of plan irregularities namely diaphragm discontinuity and re-entrant corners in the frame structure. These irregularities are created as per clause 7.1 of IS 1893:2002(part1) code. Various irregular models were considered having diaphragm discontinuity and re-entrant corners which were analysed using ETABS to determine the seismic response of the building. The models were analysed using static and dynamic methods, parameters considered being displacement, base shear and fundamental natural period. From the present study the model which is most susceptible to failure under very severe seismic zone is found, modelling and analysis is carried out using ETABS. Keywords: Diaphragm, re-entrant, static, dynamic.

Cross Section Analysis And Design is a powerful application that can perform a wide range of cross section calculations, including the design of reinforced concrete sections. The given cross sections are built up of one or more geometric entities and can be drawn directly using the versatile featured user interface. The user can also import standard steel sections from a complete shape library according to all major codes (AISC, Australian-New Zealand, BS, Chinese, European, Indian, Aluminum etc.) There are no limitations regarding the shape, materials or loads of a section, since the program can handle any arbitrary cross section under biaxial bending and axial loads. Among its capabilities, Cross Section Analysis And Design can calculate all sectional properties, plot Moment – Curvature and Interaction diagrams, estimate the location of neutral axis under given sets of biaxial loads and plot the corresponding stress – strain diagrams as well as the resulting stress contours. The last -named items can also be calculated by providing the location of the neutral axis plane on the section. Moreover, the program fully complies with all major codes concerning reinforced concrete sections (AASHTO, UBC, AS 3600, IS 456, ACI 318, BS 8110, CSA A233, EC2, NZS 3101 and CP 65). The user can also perform a reinforcement design according to above listed codes, plot the matching interaction diagrams etc., or even check a given reinforcement amount for the specified load cases. The stress – strain curve of concrete, reinforcement and other materials is specified as per the defined Analysis Parameters Sets. Thus calculations can be performed for many design situations, such as Ultimate/Serviceability or custom defined Limit States, with an automatic adjustment of the material properties, safety factors etc. A large material library is also available according to almost all concrete/reinforcement material specifications. Apart from concrete and reinforcement materials, the user can specify custom linear, bilinear, trilinear parabolic or fully general materials.

Formwork is used to shape and support concrete until it gains strength. It can be made from various materials like timber, plywood, steel, aluminum, and plastics. Timber was traditionally most common but other materials are increasingly used. Different types of formwork exist for walls, slabs, columns, etc. Proper formwork construction involves propping, shuttering, providing chambers, cleaning, and surface treatment. Formwork must be removed carefully in the proper sequence once the concrete has gained enough strength. The type of material used depends on factors like cost, availability, and need for reuse.
Cast in situ piles are concrete piles that are constructed by excavating soil and pouring concrete directly into the hole. There are several types of cast in situ piles including simplex, franki, and vibro piles. The simplex pile is most common in Bangladesh. To construct a simplex pile, a casing is installed and reinforced with rebar before concrete is poured into the casing while it is vibrated out of the ground. Cast in situ piles are preferable to driven piles in areas with noise limitations, existing structures nearby, or weak and loose soils. The construction process involves soil testing, boring, installing rebar cages, and pouring concrete through a tremie pipe.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

Note:Click the Default.edb button. This means that the definitions and
preferences will be initialized (get their initial values) from the Default.edb
file that is in the same directory as your ETABS.exe file. If the Default.edb
file does not exist in this directory then the definitions and preferences are
initialized using ETABS built-in defaults.
You should create your Default.edb file such that you most commonly click
this button.
In some cases you may want to click the Choose.edb button and specify a
different file from which the definitions and preferences are to be initialized.
For example, a certain client or project may require certain things in your
model to be done in a certain way that is different from your typical office
standards. You could have a specific .edb file set up for this client or project
which could then be used to initialize all models for the client or project. This
will allow setting of the repeatedly used preferences.
Click the No button if you just want to use the built-in ETABS defaults.

Step 3-3: Specify Reinforcement Data for Beam
Click on “Reinforcement” and specify reinforcement data as shown in the following
figure.
Note for Reinforcing Information for Beam
For concrete beams there are two types of reinforcing information that you specify.
Rebar cover is specified at the top and bottom of the beam. The top cover is
measured from the top of the beam to the centroid of the top longitudinal reinforcing.
The bottom cover is measured from the bottom of the beam to the centroid of the
bottom longitudinal reinforcing.
22. ETABS Tutorial Example ACECOMS, AIT
22/97 Seismic Analysis & Design of 10 Story RC Building (Equivalent Lateral Force)
The reinforcement overrides are specified areas of longitudinal reinforcing steel
that occur at the top and bottom of the left and right ends of the beam. These
overrides are used by ETABS as follows:
In the Concrete Frame Design postprocessor when the design shear
in a concrete beam is to be based on provided longitudinal
reinforcement (that is, the shear design is based on the moment
capacity of the beam) ETABS compares the calculated required
reinforcement with that specified in the reinforcement overrides and
uses the larger value to determine the moment capacity on which the
shear design is based.
In the Concrete Frame Design postprocessor when the minimum
reinforcing in the middle of a beam is to be based on some
percentage of the reinforcing at the ends of the beam ETABS
compares the calculated required reinforcement at the ends of the
beam with that specified in the reinforcement overrides and uses the
larger value to determine the minimum reinforcing in the middle of
the beam.
In the Concrete Frame Design postprocessor when the shear design
of columns is to be based on the maximum moment that the beams
can deliver to the columns ETABS compares the calculated required
reinforcement with that specified in the reinforcement overrides and
uses the larger value to determine the moment capacity of the beam.
For any degree of freedom in the frame nonlinear hinge properties
assigned to a concrete member that is specified as default ETABS
calculates the hinge force-deformation properties based on the larger
of the calculated required reinforcement at the ends of the beam
(assuming you have run the design through the Concrete Frame
Design postprocessor) and the specified reinforcement overrides.

Specify column section properties as shown in the following figure.
25. ETABS Tutorial Example ACECOMS, AIT
Seismic Analysis & Design of 10 Story RC Building (Equivalent Lateral Force) 25/97
Step 3-6: Specify Reinforcement Data for Column
Click on “Reinforcement” button and specify reinforcement data as shown in the
following figure.
Note for Reinforcing Information for Columns
For columns the following areas are provided in the Reinforcement Data dialog box:
Configuration of Reinforcement: Here you can specify rectangular or circular
reinforcement. You can if desired put circular reinforcement in a rectangular beam or
put rectangular reinforcement in a circular beam.
Lateral Reinforcement: If you have specified a rectangular configuration of
reinforcement then the only choice available to you here is ties. If you have specified
a circular configuration of reinforcement then you have an option of either ties or
spiral for the lateral (transverse) reinforcement.
26. ETABS Tutorial Example ACECOMS, AIT
26/97 Seismic Analysis & Design of 10 Story RC Building (Equivalent Lateral Force)
Rectangular Reinforcement: This area is visible if you have chosen a rectangular
configuration of reinforcement. The following options are available in this area.
• Cover to Rebar Center: This is the distance from the edge of the column to
the center of a longitudinal bar. In the special case of rectangular
reinforcement in a circular column the cover is taken to be the minimum
distance from the edge of the column to the center of a corner bar of the
rectangular reinforcement pattern.
• Number of bars in 3-dir: This is the number of longitudinal reinforcing bars
(including corner rebar) on the two faces of the column that are parallel to the
local 3-axis of the section.
• Number of bars in 2-dir: This is the number of longitudinal reinforcing bars
(including corner rebar) on the two faces of the column that are parallel to the
local 2-axis of the section.
• Bar size: This is the specified size of reinforcing steel for the section. You can
only specify one bar size for a given concrete frame section property.
Circular Reinforcement: This area is visible if you have chosen a circular
configuration of reinforcement. The following options are available in this area.
• Cover to Rebar Center: This is the distance from the edge of the column to
the center of a longitudinal bar. In the special case of circular reinforcement in
a rectangular column the cover is taken to be the minimum distance from the
edge of the column to a circle drawn through the center of all the rebar in the
circular reinforcement pattern.
• Number of bars: This is the number of longitudinal reinforcing bars in the
section.
• Bar size: This is the specified size of reinforcing steel for the section. You can
only specify one bar size for a given concrete frame section property.
Check/Design: In this area you specify that when a member with this frame section
property is run through the Concrete Frame Design postprocessor the reinforcement
is either to be checked or to be designed. If the reinforcement is to be checked then
all information in the Reinforcement Data dialog box is used. If the reinforcement is
to be designed then all information in the Reinforcement Data dialog box is used
except the bar size is ignored and the total required steel area is calculated. For
design the configuration of reinforcement, lateral reinforcement and cover is used.
If you specify reinforcing in a concrete column frame section property that is
specified using the section designer utility then the Concrete Frame Design
postprocessor either checks the column for the specified reinforcing or designs new
reinforcing depending on the option you selected when you specified the section.

different if you are trying to model full shell behavior for a corrugated metal deck.
The membrane thickness is used for calculating:
The membrane stiffness for full shell and pure membrane sections.
The element volume for element self-mass and self-weight
calculations.

Note:
If this check box is checked, the tributary area live load reduction method based on
Section 1607.5 of the 1997 UBC is used. The basic formula is as follows:
RLLF = 1 - 0.0008(A - 150)
where,
RLLF = The reduced live load factor for an element, unitless. The RLLF is
multiplied times the unreduced live load to get the reduced live
load.
A = Tributary area for the element, ft2
. If A does not exceed 150 ft2,
no
live load reduction is used. See Tributary Area for more
information.
The RLLF factor can not be less than the minimum factor described in the Minimum
Factor Area description.
Note that no check is done to limit the RLLF based on Equation 7-2 in Section
1607.5 of the 1997 UBC.

15.Run Shear Wall Design and View Results
Typical Shear Wall Design Procedure
Following is a typical shear wall design process that might occur for a
new building. Note that the sequence of steps you may take in any
particular design may vary from this but the basic process will be
essentially the same.
1. After create the building model Use the Options menu Preferences
Shear Wall Design command to review the shear wall design
preferences and revise them if necessary. Note that there are default
values provided for all shear wall design preferences so it is not actually
necessary for you to define any preferences unless you want to change
some of the default preference values.
2. Run the building analysis using the Analyze menu Run Analysis
command.
3. Assign the wall pier and wall spandrel labels. Use the Assign menu
Frame/Line Pier Label, the Assign menu Shell/Area Pier Label,
the Assign menu Frame/Line Spandrel Label, and the Assign
menu Shell/Area Spandrel Label commands to do this.
Note that the labels can be assigned before or after the analysis is run.
4. Assign shear wall overwrites, if needed, using the Design menu Shear
Wall Design View/Revise Pier Overwrites and the Design menu
Shear Wall Design View/Revise Spandrel Overwrites commands.
Note that you must select piers or spandrels first before using these
commands. Also note that there are default values provided for all pier
and spandrel design overwrites so it is not actually necessary for you to
define any overwrites unless you want to change some of the default
overwrite values.
Note that the overwrites can be assigned before or after the analysis is
run.
Important note about selecting piers and spandrels: You can select a
pier or spandrel simply by selecting any line or area object that is part of
the pier or spandrel.

5. If you want to use any design load combinations other than the default
ones created by ETABS for your shear wall design then click the Design
menu Shear Wall Design Select Design Combo command. Note
that you must have already created your own design combos by clicking
the Define menu Load Combinations command.
6. Click the Design menu Shear Wall Design Start Design/Check of
Structure command to run the shear wall design.
7. Review the shear wall design results. To do this you might do one of the
following:
a. Click the Design menu Shear Wall Design Display Design
Info command to display design information on the model.
b. Right click on a pier or spandrel while the design results are
displayed on it to enter the interactive wall design mode. Note
that while you are in this mode you can revise overwrites and
immediately see the new design results.
If you are not currently displaying design results you can click the
Design menu Shear Wall Design Interactive Wall Design
command and then right click a pier or spandrel to enter the interactive
design mode for that element.
1. Use the File menu Print Tables Shear Wall Design command to
print shear wall design data. If you select a few piers or spandrels before
using this command then data is printed only for the selected elements.
2. If desired, revise the wall pier and/or spandrel overwrites, rerun the shear
wall design, and review the results again. Repeat this step as many
times as needed.
3. If desired, create wall pier check sections with user-defined (actual)
reinforcing specified for the wall piers using the Section Designer utility.
Use the Design menu Shear Wall Design Define Pier Sections for
Checking command to define the sections in Section Designer. Be sure
to indicate that the reinforcing is to be checked. Use the Design menu
Shear Wall Design Assign Pier Sections for Checking command to
assign these sections to the piers. Rerun the design and verify that the
actual flexural reinforcing provided is adequate.
89. ETABS Tutorial Example ACECOMS, AIT
Seismic Analysis Design of 10 Story RC Building (Equivalent Lateral Force) 89/97
4. Assign these check sections to the piers, change the pier mode from
Design to Check, and rerun the design. Verify that the actual flexural
reinforcing provided is adequate.
5. If necessary, revise the geometry or reinforcing and rerun the design.
6. Print or display selected shear wall design results if desired.
Note that shear wall design is performed as an iterative process. You
can change your wall design dimensions and reinforcing during the
design process without rerunning the analysis. However, you always
want to be sure that your final design is based on analysis properties
(wall dimensions) that are consistent with your design (actual) wall
dimensions.
