Abstract
As we all knows most of the building constructed as an irregular configuration both in plan and elevation. The most devastating and unpredictable natural disaster is the earthquake. Earthquake can give very sever effect on irregular configuration of building. For the better behaviour of structure in earthquake, the structure should be simple and regular and also it has adequate lateral strength, stiffness, ductility. It is necessary to design the structure to withstand against earthquake. Irregularity used in models are as per new code of earthquake IS 1893:2016(part1). The paper discussed on behaviour of building having plan and vertical irregularity. For whole study irregularities used are Torsional, Re-entrant corner, floor slabs having excessive cut-outs or opening, Out of plane offset in vertical element, Non-parallel lateral force system, Mass, Vertical geometric irregularity, stiffness irregularity, stub column, In-plane discontinuity in vertical element resisting lateral force.
