Project 1_Comparative study of different storey buildings for Seismic forces

Comparative Study of Different Story Buildings for Seismic Forces

AIM: TO MODEL AND ANALYZE MULTIPLE BUILDINGS WITH DIFFERENT FLOOR LEVELS AND DESIGN PARAMETERS USING ETABS SOFTWARE AND COMPARE THE RESULTS TO UNDERSTAND THEIR OVERALL SEISMIC BEHAVIOUR.

INTRODUCTION:

The structural configuration of the building plays a major role in determining the overall response during an earthquake. Different building geometries behave differently when induced by the same seismic forces. Hence, it is very important to properly understand the response of buildings related to their structural configurations for a safer design approach. Therefore in this project, we have modeled different buildings with varying geometries using ETABS. Furthermore, their responses are analyzed with the help of the software and the results are then compared to grasp an understanding of the structural behavior of buildings with different storeys.

DETAILED PROCEDURE:

For an easier approach, this project is divided into two phases. In the first phase, we have covered the modeling part of the buildings where the structures are drawn from scratch as per the pre-specified geometrical and structural conditions. Moreover, running the analysis and generating the structural output with regard to all the buildings is also covered in the first phase itself.

Moreover, a comparative analysis of the structural results obtained in the first half is executed in the second phase of this project. And based on the comparative results, various structural properties of the buildings pertaining to their seismic response are concluded.

Conclusion:

It is evident that pinned support offers fewer restraints compared to the fixed one which leads to more movement and thus increased natural period. As a result, it can be concluded that the fixed support will give you better control over the fundamental natural period of buildings.
