Abstract:

Nowadays performance based engineering design philosophies are gaining more attention. This study investigates the performance assessment of multi-storeyed moment resisting frames. Push over analysis was used to understand the behaviour of the structures in zone V during an earthquake. Effect of increase in the number of bays and number of stories on seismic performance was studied. Study was carried out for storey heights 3, 3.5 and 4m. 27 building models were created and analysed using ETABS 9.7 software. Parameters like displacement, base shear and time period of these models were chosen for comparison. It was observed that as the number of storey and storey height increased base shear and spectral acceleration is reduced, where as displacement, time period and spectral displacement increased. When number of bays increased base shear and time period increased and spectral acceleration decreased .Analysis shows the location of plastic hinges at performance point of the structures, overall performance of most of the building models lied between the life safety and collapse prevention level.
