Parametric Studies on the Seismic Behavior of Irregular Structures

Irregular structures subjected to earthquake loads demand attention as they behave differently from regular ones. The number of irregular buildings being constructed is increasing yearly. Irregularities are unavoidable in certain cases, whereas in some other cases they are architecturally planned. Design of frame configurations incorporating such irregularities without compromising the performance of the structure needs detailed investigation on the parameters that influence the structural behavior. In this study, parametric studies are carried out in order to understand the effect of the type, degree, and location of irregularity on the behavior of structures. All these factors are found to affect the response of the structures significantly. The parameters such as mass, total cross-sectional area of columns, and storey height are considered for this study.
