Seismic Rating of Multistoried Frame System by Non-Linear Pushover Research

Abstract

This paper compares multistoried frame structures on plain ground and on hilly areas, first under the action of normal commercial loading and thereafter by considering the effect under the action of heavy loads. Behavior of multistoried frame buildings on plains are completely different from buildings which are constructed on hilly slopes. Buildings constructed on plain is simple and symmetrical, whereas the buildings that are constructed on hilly slopes are complex in geometry and asymmetrical in nature. Similarly, the behavior of commercial buildings with normal loading is distinctively different in comparison to special buildings such as Data centre buildings which are heavily loaded under gravity. Four different types of Symmetrical and Asymmetrical analytical Models are generated for five and ten storey buildings using "ETABS". Seismic evaluation of these models is done separately under the effect of normal and heavy loading by performing Nonlinear Pushover analysis.
