Seismic analysis of structures is an important branch of civil engineering which deals with the calculation of the response of a structure subjected to seismic loads. The buildings are mainly classified into two types regular and irregular buildings. Now a days in the urban areas there is a rise in the number of the irregular buildings as the space available for the construction of structures is limited. In the irregular buildings there is a lack of symmetry and they have discontinuity in the geometry, mass and load resisting elements. The irregularities in the structure are broadly classified as plan irregularity and vertical irregularity. In this paper the building with plan irregularities along with the effect of variation in rigidity of diaphragms and effects of orientation of columns on seismic response of a structure is studied. This paper particularly discusses the variation in bending moment and lateral displacement at different positions in the Box and L-shape structural model with a different diaphragm condition under the action of incremental horizontal seismic forces along MUTUALLY perpendicular direction. The analysis of the structural model is done by using ETABS 2015 software by considering the static non-linear analysis also called as pushover analysis.
