A structure can be classified as irregular if it contains irregular distributions of mass, stiffness and strength or due to irregular geometrical configurations. The behavior of any building depends on the arrangement of structural elements present in it. The important aspects on which the structural configuration depends are geometry, shape and size of the building. In reality, many existing structures contain irregularity due to functional and aesthetic requirements. In this proposed work, the structural analysis and design of G + 20 storey reinforced concrete symmetrical and asymmetrical structures is done with the help of Staad-Pro software. Irregular plan of the structure (E, L, T, and Y shape) and regular plan (Rectangular shape) of the structures are considered. These buildings have approximately area of about 620m2. The building is assumed to be sited in seismic zone III on a site with medium soil and Special Moment Resisting Frame are evaluated and compare Basic parameters such as shape factor, modal analysis, deflection, storey drift. Response spectrum analysis method is used for analysis.

Irregularity, Geometry, shape factor, modal analysis, deflection, storey drift etc.
