Abstract
The seismic behavior of buildings critically depends on its overall size, shape and configuration. Buildings with re-entrant corners in plan are considered to be irregular by many seismic design codes. Of the various irregular shaped buildings, H-shape is one of the most vulnerable and commonly used floor plans with re-entrant corners. The seismic behavior of RC buildings (Hshape) with symmetrical floor plan having re-entrant corners with shear wall as seismic resisting element is investigated in this paper. Various types of building plan configurations with shear walls at different locations are studied. These buildings are modeled and analyzed using ETABS 2015 software. A building without shear wall is also modeled as a bench mark problem to compare all other models with this. Time history analysis has been carried out for all these models located in Vijayawada. Bhuj earthquake ground acceleration data recorded at Ahmedabad station is given as input acceleration for time history analysis. Various dynamic response parameters such as Story displacement, Story drift are compared and some useful conclusions are drawn.
