Checklist - Modelling in ETABS

Checks - I Checks for preparation of modal Summary (see details for further information)

A)

Units KN-m

Change the unit to KN-m and the far right bottom dialog box.

B)

Concrete Frame Design Define material property Defining frame sections & Reinforcement details

Go to Options>Preferences>Concrete Frame Design and select the design code as IS 450-200 Define the proper material as required e.g. M 20, 25, 30 etc.

Define frame sections as required and carefully put in the reinforcement details like cover, no of bars in each direction and size of steel bars. While defining frame sections, - Column C3045 shall mean depth = 0.30 & width = 0.45 - Beam B2330 shall mean depth = 0.30 & width = 0.23 A total of four earthquake load cases i.e. two in each direction with 0.05 eccentricities in each direction are to be made. Earthquake loads are to be defined as per the given area’s seismic zones as defined by IS 1893. The sequence of earthquake loads should be as follows : 1. EQXP 2. EQYP 3 .EQXN 4. EQYN Change column’s base points to rigid. Turn on the beam sections to check if beam is broken at correct points Turn on auto area mesh and then toggle shrink to check meshing of membrane slabs All non-continuous secondary ends of beams are to be released of M 3-3. Cantilever ends are not to be released. After creating/drawing all the lines elements select all the beams and assign them 13 output stations. Wall load on beam is to be calculated for the height H – 0.3 where H is the height till next beam above it. Change them accordingly if height is changed. Add default design combos AnalyzeCheck ModelTick all boxes & tolerance for checks should be 0.1m / 100 mm
