Comparative Study of Seismic Performance of Building Having Mass Vertical Irregularity at Different Floor Levels

Manoj Kumar ^[92] | Dr. Venkata G Babu

Abstract: Nowadays, as in the urban areas the space available for the construction of buildings is limited. So in limited space we have to construct such type of buildings which have can be used for multiple purposes such as lobbies, car parking etc. To fulfill this demand, buildings with irregularities is the only option available. During an earthquake, failure of structure starts at points of weakness. This weakness arises due to discontinuity in mass, stiffness and geometry of structure. Vertical irregularities are one of the major reasons of failures of structures during earthquakes. To study the behaviour of the building having various vertical irregularities at different floor levels six models have been considered in this project. All the models were analyzed by using SAP 2000. The methods used for the analysis are static method and response spectrum method.
