Asymmetric buildings under earthquake excitations have a greater vulnerability compared to symmetric buildings. Torsional provisions of codes are based on the stiffness eccentricity, while effects of strength eccentricity on torsional response are also considerable. In recent studies which have been accomplished, it is concluded that yield displacement of structural walls is related to dimensions and yield strain of reinforcing steel. Therefore, the stiffness of the wall elements depended on the assigned strength and yield displacement. Different locations of strength and stiffness eccentricities to each other, is very effective on the torsional response variations. In near-fault motions researches, two main objectives are considered. In the first case, component characteristics of near-fault motions and equalizing fault-normal component with equivalent pulse are considered. While, the second case provides quantitative knowledge on response structures subjected to near-fault ground motions. In this study, based on the proposed procedure, torsional response of structure models which have different distributions of the strength and stiffness eccentricity under near-fault and far-fault excitations are considered. Since fault-normal components have large pulse period in the beginning of velocity time history, effects of pulse period on seismic responses are evaluated. The effects of near-fault and far-fault motions on torsional response in the different stories are also considered. Displacement demands on stiff side and soft side, story drift and story ductility demand under mentioned ground motions are calculated and compared. Moreover, strength effects by considering different reinforcing ratios are evaluated.
