Structural Modelling using Etabs 2018

PROCEDURE

Open etabs and select new model and make the following settings.
click the custom grid spacing and maintain the spacing as per Drawing in both x and y direction.
click ok, a box appears, enter the stories up to G+7 maintain height of 3m
now go to define and select material properties, and enter the following.
M30 grade concrete and steel 500
now go to section properties and enter the size of beam column and slab.
now go to the load pattern, and enter the loads as shown.
now select the quick draw column from the screen and place the columns at each grid.
similarly place the beams and slabs.
now assign the load to roof slab, select all the slabs and go to assign option.
select the load as live load & Dead Load of flooring tiles & Mortar of flooring & Ceiling Plaster
for other floors assign
now assign the load to all the beams
now go to define option and select mass source and assign the mass source as shown.
go to the load combination and select modify, a list of combination appears.
go to the shells from assign and then select diaphragm, assign as D1.
now go to the analyze and check model.
since there are no errors, building looks like this after applying loads.
go to the display and select shown tables and then modal mass participating ratios.
table is obtained.
from the table we can say that time period of mode of torsion is less than fundamental mode.
