Analysis of the Behaviour of soft storey Building using E tab software

Avinash Mishra

Abstract :

<p>&nbsp;Soft storey buildings are multi-story buildings which have one or more floors &ldquo;soft&rdquo; due to its structural design. Soft storeys are much unsafe in earthquakes, because they cannot survive due to lateral forces and thrust developed by the shaking action of the earthquake. As a result, the soft storey may fail, causing what is known as a soft storey collapse. After a major earthquake, there was lot of collapse of buildings structures, which we have shown soft storey collapse, as it is the one of the common leading causes of damage to structures. To analyze the effect of earthquake on soft storey building, a building model of twelve storeys with different soft storey were analyzed. Analysis is also done for a full infill &amp; bare frame. Analysis was carried out using E-tab analysis. E-TABS is a software that helps in analysis and design of multi-story building. Basic or advanced systems under static or dynamic conditions may be evaluated using E-TABS. As a result of this analysis, we found that soft storey at lower level is much vulnerable in comparison of upper soft storeys</p>
