Modelling of 25 storey building with the specified properties using ETABS

AIM: ETABS modelling of a 25 Storey building

procedure:

1.first open the new modal

2.modal initialization setting

use built-setting = metric -SI

steel section data base- India

concrete code -IS-456:2000

steel code-IS-800-2007

3.custom the girds and Storeys required numbers and set the master Storey as 1st floor and similar for remain Storeys

4. define the properties

add new materials

concrete is M30 grade

rebar is 415 HYSD bars

5. define the section frames and add the beam is 300x400mm, and column as 800x800mm

6.define section slab set the thickness as 150mm

define the load patterns and set the dead load live and wall, seismic as Eqx and EQY similarly eqx+, eqx-, eqt+,eqy-

add the columns at grids and beams and replicate negative direction of y-axis and x-axis

-load combination set the auto default as concrete

-select the beams and add the super dead load of wall is 10kn/m

-and select the slab add the live load as 3kn/m^2

after the everything complete un analysis and save the file in folder

after completion the run analysis open the tables and check the condition given

modal participation factor is more than 60% firs three modes together should be contributed

4.
