ANALYSIS AND DESIGN OF HIGH RISE BUILDING BY USING ETABS

INTRODUCTION
• From a structural engineer's factor of view the
tall constructing or high upward thrust
constructing (HRB) may be outlined in concert
that, with the inside the structural type.
• The growth in latest multi storeyed
constructing development, which began in
late nineteenth century, is meant for
essentially the most part for industrial and
residential features.

INTRODUCTION
• Tall buildings are the fundamental evolved
engineered structures considering there are a
few conflicting necessities and problematic
constructing techniques to integrate
• In these day’s tall constructions are getting
extra and additional slim ensuing in the hazard
of further sway as compared with earlier high-
rise structures.

ETABS
• The innovative and revolutionary new ETABS is
that the final integrated software package for
the structural analysis and style of buildings.

ETABS
• ETABS offers unmatched 3D object primarily
based modeling and visualization tools,
blazingly quick linear and nonlinear analytical
power, subtle and comprehensive style
capabilities for a wide-range of materials, and
perceptive graphic displays, reports, and
schematic drawings that enable users to
quickly and simply decipher and perceive
analysis and style results.

ETABS
• ETABS provides an unequaled suite of tools for
structural engineers designing buildings,
whether they are working on one-story
industrial structures or the tallest commercial
high-rises.
A. Modeling of Structural Systems
B. Loading, Analysis, and Design
C. Output, Interoperability, and Versatility

STATEMENT OF PROJECT
• A notion of 24.14m×20.627m plan is taken
into idea having 16×12 bays on each the sides.
• The excessive rise constructing (HRB) of 30
stories inside which flooring to flooring top is
taken as 3m.
• Ground to ground peak is 3.5m for all of the
models.

CODES
• IS-456:2000:DESIGN CODE FOR RCC STRUCTURES
• SP-16 : DESIGN CODE FOR COLUMNS
• IS-875(PART 1) : FOR DEAD LOADS
• IS-875(PART 2) : FOR IMPOSED LOADS
• IS-875(PART 3) : FOR WIND LOADS
• IS1893:2002 : FOR EARTHQUAKE LOADS

MATERIAL DETAILS
• GRADE OF CONCRETE : M-30
• TYPE OF STEEL : Fe-500
• BRICK MASONARY : FIRST CLASS

GEOMETRICAL DETAILS
• Depth of foundation : 3 Mts,
• Floor to Floor height : 3 Mts,
• Ground floor hright : 3.5 Mts,
• Slab thickness : 120 mm
• External wall thickness : 230 mm
• Internal wall thickness : 125 mm

MODELING IN ETABS
STEPS
1. Open ETABS program.
2. Check the units of the model in the drop-
down box in the lower right-hand corner of
the ETABS window click the drop-down box
to set units to KN-m.

3. Click the File menu > New model command

4. The next form of Building Plan Grid System
and Story Data Definition will be displayed after
you select NO button.

5. Define the design code using Options >
Preferences > Concrete Frame Design command

6. This will Display the Concrete Frame Design
Preference form as shown in the figure.

7.1. Click the Define menu > Material Properties

7.2 Add New Material or Modify/Show Material
used to define material properties

8. Define section columns and beams using
Define > Frame section

To define a slab as membrane element and one
way slab define using special one way load
distribution

10. Generate the model Draw beam using
Create Line Command and draw column using
Create Column command

11. Slab is created using 3 options in which 1st
draw any shape area, 2nd draw rectangular area
and 3rd create area in between grid line

12. Model showing plan 3d view of high rise
building without bracings in linear analysis

building without bracings in linear analysis

13. Define various loads (Dead load, live load,
wind load, Earthquake load)

14. Dead Load: self weight multiplier is used 1
to calculate dead load as default. Live load or
any other define load 1st select the member
where assign this load than click the assign
button.

15. Assign point load and uniform distributed
load Select assigning point or member element
than click the assign button

16. Assign support condition Drop-down box in
the lower right-hand corner of the ETABS
window, Select only bottom single storey level
to assign fixed support using assign >
Joint/Point>Restrain (Support) command

17. In building, slab is considered as a single
rigid member during earthquake analysis. For
that, all slabs are selected first and apply
diaphragm action for rigid or semi rigid
condition.

18. Mass source is defined from Define > mass
source command
