The document discusses high rise buildings and their structures. It defines high rise buildings as between 35-100 meters tall or 12-39 floors. Buildings over 100m are called skyscrapers and over 600m are mega-tall. High rises are constructed to address land scarcity in urban areas and increasing demand for space. Their structures have evolved from early stone and iron frames to steel skeleton frames to reinforced concrete shear walls and core structures. Foundations must transfer enormous loads into the ground through methods like raft or pile foundations. Interior structures use rigid frames, shear walls, and exterior structures employ tube systems to resist lateral wind and seismic loads.
Framed structures are building skeleton frameworks formed by columns and beams. There are two main types: in-situ reinforced concrete frames and prefabricated frames. Rectangular framed structures use columns and beams arranged at right angles to support floors, walls, and roofs. They are commonly used for multi-story buildings like offices, schools, and hospitals. Framed structures provide large open floor plans and are adaptable to different shapes. Earthquake-resistant features in framed structures include shear walls, moment-resisting frames, and braced structures which resist lateral forces during seismic activity.

Formwork is a temporary mold used to contain poured concrete until it cures and can support itself. It needs to be strong enough to support the weight of wet concrete and withstand pouring and compaction loads. New materials like steel and plastics are now used for formwork in addition to wood. Slipforming allows for continuous vertical pouring of concrete structures like building cores without relying on external support, by using a formwork that rises slowly on its own as concrete is added.
Steel is a versatile material that is commonly used for large scale construction projects due to its strength, durability, and cost-effectiveness. Steel trusses are a type of structure frequently employed in buildings to provide support for roofs, floors, and other loads. They consist of compression and tension elements arranged in a triangulated pattern, allowing them to efficiently span long distances with minimal material. Common types of steel truss designs include Pratt, Warren, and Fink configurations. Truss members are often made of angles, channels, tubes, or other standard steel sections joined together with bolted or welded connections.

solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs
Sri Guru Hargobind Ji - Bandi Chor Guru.pdfBalvir Singh
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days

Consolidation Settlement Calculation Program-The Python Code
By Professor Dr. Costas Sachpazis, Civil Engineer & Geologist
This program calculates the consolidation settlement for a foundation based on soil layer properties and foundation data. It allows users to input multiple soil layers and foundation characteristics to determine the total settlement.
3. RCC COLUMN
• A column is a vertical member which effectively takes load by compression. Basically column
is a compression member as load acts along its longitudinal axis. Bending moment may occur
due to wind earthquake or accidental loads.
• Column transfers the load of the structure of slabs beams above to below, and finally load is
transferred to the soil. Position of the columns should be so that there are no tensile stresses
developed at the cross section of the columns. Columns location should be such that it hides in
the walls partially or fully.
Long Column/ Slender Short Column Intermediate Column
TYPES OF COLUMN
DESIGN
RCC columns are mainly constructed in four different stages, which are
1. Column Layout Work.
2. Column Reinforcement Work.
3. Column Formwork and
4. Pouring Concrete,
3. COLUMN FORMWORK:
The floor height is normally kept at 10 feet. If the
slab contains beam, then concrete has to be poured
upto the beam bottom level. For example, if the
beam height is given in the drawing is 1′-6″, the
casting height of column and formwork will be 8′-
6″. But as we know that dropping concrete more
than 5 feet height is not allowed because it will
cause segregation, we should create formwork
within 5 feet height. When the first part will be cast
completely, the rest part should be started
.
4. POURING CONCRETE INTO COLUMN:
Concreting of column is done in two different
methods
1. Manually
2. Using machine or pump.
1. COLUMN LAYOUT WORK:
This is the first step of column construction. In this
step, the location of columns is decided practically
in the field. It is done by laying rope as per the
grids are shown in the drawing and afterward, the
location of columns are marked.
2. COLUMN REINFORCEMENT WORK:
When marking of column location is done, the
reinforcement of columns are placed according to
the structural drawing.
For example, C1-12#16 mmØ and stirrup-10
Ø@4″c/c.
4. BEAM
Beam is a structural member which is normally placed horizontally. It provides resistance to bending
when loads are applied on it.
Various types of materials such as wood, steel, aluminum, etc are used for constructing beam. Most
commonly used material for beam is RCC (Reinforced Cement Concrete).
RCC beam can be various types depending on different criteria. Such as, depending on shape, beam
can be rectangular, T-beam, etc. Depending on reinforcement placement, beam can be double
reinforced beam, single reinforced beam, etc.
RCC beams are 4 types depending on their supporting systems.
1. Simply supported beam
2. Semi-continuous beam
3. Continuous beam, and
4. Cantilever beam.
• A beam is a structural element that primarily resists loads applied laterally to the beam’s axis. Its
mode of deflection is primarily by bending. The loads applied to the beam result in reaction
forces at the beam’s support points. The total effect of all the forces acting on the beam is to
produce shear forces and bending moments within the beam, that in turn induce internal stresses,
strains and deflections of the beam. Beams are characterized by their manner of support, profile
(shape of cross-section), length, and their material.
• When beams support slabs, they work together forming a “T” section beam. The level of the
slabs compared to the level of the beams results in the formation of rectangular beams, inverted
beams or “Z” beams.
• The beam to column connection is called direct support while the beam to beam connection is
called indirect support.
• The most usually used beam is the one supported by two columns and the most rarely used is
the cantilever beam. Indirect supports should be ocasionly used and only if it’s the only
avaible solution.
FUNCTION
5. SLAB
• A Reinforced Concrete Slab is the one of the most important component in a building. It is a
structural element of modern buildings. Slabs are supported on Columns and Beams.
• RCC Slabs whose thickness ranges from 10 to 50 centimetres are most often used for the
construction of floors and ceilings.
• Thin concrete slabs are also used for exterior paving purpose.
• In many domestic and industrial buildings a thick concrete slab, supported on foundations or
directly on the sub soil, is used to construct the ground floor of a building.
• In high rises buildings and skyscrapers, thinner, pre-cast concrete slabs are slung between the
steel frames to form the floors and ceilings on each level.
• While making structural drawings of the reinforced concrete slab, the slabs are abbreviated to
“r.c.slab” or simply “r.c.”.
Design of various types of slabs and their reinforcement
•Corrugated, usually where the concrete is poured into a
corrugated steel tray. This improves strength and prevents
the slab bending under its own weight. The corrugations run
across the short dimension, from side to side.
•A ribbed slab, giving considerable extra strength on one
direction.
•A waffle slab, giving added strength in both directions.
Reinforcement design
•A one way slab has structural strength in shortest
direction.
•A two way slab has structural strength in two directions.
Construction
•A concrete slab can be cast in two ways: It could either be prefabricated or cast in situ.
•Prefabricated concrete slabs are cast in a factory and then transported to the site ready to be
lowered into place between steel or concrete beams.
•They may be pre-stressed (in the factory), post-stressed (on site), or unstressed. Care should be
taken to see that the supporting structure is built to the correct dimensions to avoid trouble with
the fitting of slabs over the supporting structure.
•In situ concrete slabs are built on the building site using formwork. Formwork is a box-like
setup in which concrete is poured for the construction of slabs.
•For reinforced concrete slabs, reinforcing steel bars are placed within the formwork and then
the concrete is poured.
•Plastic tipped metal, or plastic bar chairs are used to hold the reinforcing steel bars away from
the bottom and sides of the form-work, so that when the concrete sets it completely envelops
the reinforcement.
•Formwork differs with the kind of slab. For a ground slab, the form-work may consist only of
sidewalls pushed into the ground whereas for a suspended slab, the form-work is shaped like a
tray, often supported by a temporary scaffold until the concrete sets.
6. STAIRCASE
RCC stairs may be the most common stairs widely used than any other types of stair. These stairs
can be easily moulded to any desired shape and are better wear and fire resistant. The steps of RCC
stairs are made by using ordinary cement concrete. Besides ordinary cement concrete, some other
superior finishing materials are also used such as marble, terrazzo, tiles etc. to give them better
appearances.
ADVANTAGES OF RCC STAIRS:
The advantages of R.C.C stairs are as
following:
1. R.C.C stairs are better fire resistant than any
other stairs.
2. They are adequately strong and more
durable.
3. The steps are non-slippery.
4. They offer better and pleasant appearances.
5. The stairs can be designed for greater widths and longer spans.
6. They can be easily cleaned.
7. R.C.C stairs can be precast or cast in situ.
8. The maintenance cost is almost nil.
9. In modern sky scraper construction always framed structures are adopted, for such structures
R.C.C stairs are the one and only stairs which can be used.
• DIFFERENT STAIR ARRANGEMENT IN
CASE OF R.C.C. Single Straight Flight Stairs
• Inclined Slab Stairs With Half Space Landings
• String Beam Stairs
• Crancked Slab Stairs
• Crancked Slab Stairs
• Cantilever Stairs
• Spiral Stairs
7. LINTEL
A lintel is one type of beam which used to support the above wall when openings like doors, windows
etc. are necessary to provide a building structure. The main function of the lintel is to take loads
coming from above wall and transfer its load to the side walls. The lintel beam generally ends into the
masonry wall so as to convey the weight carried by them to the masonry walls and its width is same
to the wall width. The lintel can also be used as decorative architecture element.
Types of Lintel
Lintels are classified into the following types
according to the materials of their construction:
1.Timber lintel
2.Stone lintel
3.Reinforced concrete lintel
4.Brick lintel
5.Reinforced brick lintel
6.Steel lintel
CHAJJA.
Chajja is Hindi word for Eaves, a chhajja is the
projecting or overhanging eaves or cover of a roof
usually called a sunshade supported on large carved
brackets or projected as a cantilever from walls.
An overhang in architecture is a protruding
structure which may provide protection for lower
levels.
Functions of Chajja
1.Protects from external sunlight.
2.Protects from rainwater
3.as aesthetics to a building
4.a recess place to keep utilities like A.C
compressor
CANOPY
A canopy is a layer of something that spreads out
and covers an area. A canopyis an overhead roof or
else a structure over which a fabric or metal
covering is attached, able to provide shade or shelter
from weather conditions.
•Canopy:- A canopy is an overhead roof or else a
structure over which a fabric or metal covering is
attached, able to provide shade or shelter from
weather conditions such as sun, hail, snow and rain.
1.It provide an elegance beauty to structure
2.It maybe a temporary offset or structure provided
in the building for special reason.
8. COFFER SLAB
A ceiling in which the beams and cross-beams leave
a regular pattern of square or multi-sided sunken
panels, or coffers, each of which is often decorated
with molded, carved and painted decoration.
COFFER CEILINGS
A Coffer (or coffering) in architecture, is a
sunken panel in the shape of a square,
rectangle, or octagon in a ceiling,soffit or vault.
A series of these sunken panels were used as
decoration for a ceiling or a vault, also called
caissons('boxes"), or lacunaria ("spaces,
openings"), so that a coffered ceiling can
be called a lacunar ceiling: the strength of the
structure is in the framework of the coffers.
SERVICES IN COFFERED SLAB
1.The coffer blocks used in the Coffer Slab
are manufactured from plastic, making them
light and easy to handle.
2. The assembly of the coffer blocks is done
on the ground before being lifted into position
between the supporting ribs. The result is
less labor and quick and easy installation.
A pergola is an outdoor garden feature forming a
shaded walkway, passageway, or sitting area of
vertical posts or pillars that usually support cross-
beams and a sturdy open lattice, often upon
which woody vines are trained. The origin of the
word is the Late Latin pergola, referring to a
projecting eave.
Pergolas may link pavilions or extend from a
building's door to an open garden feature such as an
isolated terrace or pool. Freestanding pergolas, those
not attached to a home or other structure, provide a
sitting area that allows for breeze and light sun, but
offer protection from the harsh glare of direct
sunlight. Pergolas also give climbing plants a
structure on which to grow.
