Linear elastic seismic performance of RCC buildings with irregular plan.

Due to various constraints, it is not always possible to have a regular configuration of a building. This leads to different irregularities in the building. In this study, a set of RCC buildings having irregular plan configuration have been studied. The seismic performance of the structures has been studied using response spectrum method of seismic analysis wherein the response spectrum specified in IS 1893-2016 has been used. The effect of stiffness modifiers as specified in the IS 1893-2016, for the framing elements, on the seismic performance of the buildings has been also studied. The buildings have been designed as per IS 456 and IS 1893. The seismic performance has been evaluated in terms of storey displacements, storey drift, base shear, storey shear and time period for various values of irregularity in plan. [ABSTRACT FROM AUTHOR]
