A Study On Tall Structure With Soft Stories At various Level By Non-Linear Analysis

Abstract

Now a days as population in cities is increasing day by day there is a big problem for parking of vehicles in tall
building .This issue can be solved by providing the soft storey in each building .One lesson which we have learnt from past
earthquake is that building sustain less damage when its plan and geometric configuration are as simple as possible.
Providing a first open storey in multi-storeyed building is very common now a days. In seismic active areas it is highly
undesirable to provide soft storey in a building which has been verified in numerous experiences from past earthquak
In this project the modeling is done with software ETABS v9.70 for the analysis of tall structure with soft storey at
various floor levels. The building with G+25 is taken into consideration for study. In this project six (6) models of zone-5
are created. The performance of the building is studied by considering 2nd storey, 7th storey, 12th storey, 17
th
storey, 22
nd
storey and 27
th
storey as a soft storey. Push over analysis is carried out to know the characteristics points of the building
with soft storey.
