Abstract

The main objective of this study is to estimate seismic demands of MDOF frames, using SDOF system demands and to presents a procedure to evaluate maximum story drift and ductility demands of MDOF STEEL MOMENT RESISTING Frames. Some modifications have been studied, in order to evaluate MDOF system demands, including higher modes. These modification factors are computed as the ratios between MDOF and the first mode SDOF seismic demands for each record, making them independent from the intensity and duration of ground motion. This permits the statistical averaging of modification factors computed for ground motions of different intensities and duration. The results of this study show that the distribution of story drift and dynamic ductility demand over the height of the frames (specially high-rise ones), have an irregular trend. The reason is attributed to higher modes and MDOF effects, which is intensified with increasing the structure height and fundamental period. It was also concluded that the amplification of deformation demands (story drift and ductility respresented by adH.M and aµH.M modification factors), are mostly increasing with fundamental period and level of ductility (µSDOF).
