Abstract
Due to the architectural demand and usage of building in present scenario many building have irregularity in plan and elevation. Such type of building having plan irregularity in terms of slab opening is more susceptible to earthquake forces. Openings in slab can be provided to fulfil purposes like staircase, architectural aspects, lighting etc. Discontinuity in slab increases stress at discontinues joints. In this paper an attempt is made to study effect of plan irregularity over seismic forces for different plan shapes and percentage of openings in slab.
