PARAMETERS FOR ANALYSIS AND DESIGN

The mathematical models developed are subjected to dead load, live load, wind load and earthquake
load to analysis and design using ETABS VERSION 9.5 software. In this term we are taking
maximum deflection according to DCON 6 wind combination (DCON 6 = 1.5 DL + 1.5 WL). In 30
story building we have compared different models (Models A1, B1, C1, D1) with respect to
displacement.

RESULTS

The analysis and design results for different models are shown in tabular and graphical form, their
results are compared with each other. Notation “D” is used for deflection in showing the results in the
tabular form: D - Displacement in mm
