Structural Modelling using Etabs 2018

1. AIM - Structural Modelling using Etabs

Procedure -

As given open the ETAB and Draw a plan as given in attachment i.e architectural plan

Then Draw cloumn, beam, floor, Slab

First select Story and grid as per given architectural drawing

then define material and section properties in it

then select beam column and shear wall option and place at its position

then add load cases and combination then modal cases and diaphragm

then run analysis for earthquake and result is below

Base reaction

modal period and frequency

modal mass ratio

now save as this file and in that delet EQ and add response spectrum

run analysis and result as follow

base reaction

modal period and frequency

modal mass ratio

All result analysis

Modal mass participation for first 3 mode - Achived in both axis x and y .

Mode 1 and mode 2 differ by 10% - Achived

Principal mode br greater than Torsional Mode - Achived

Axial Stress between column and shear wall - Achived
