عنوان مقاله [English]
In this study, the performance of resistant skeleton of mid-rise moment frames under scaled near-field earthquake records have been evaluated by using both, incremental dynamic and nonlinear dynamic time history analyses. Also, a brief explanation of this concept through the perspective of the formation of nonlinear hinges has been studied using modal pushover analysis. Three-dimensional propagation of seismic waves in resistant skeleton of buildings create a set of dynamic lateral forces with different intensities in the height of structure. Near-field strong ground motions are able to magnify the intensity of the mentioned forces. The studied structural models are comprising of bundled tube frame and full 3d moment frame resistant skeletons. The evaluated response parameters are the maximum interstory drift, maximum acceleration of stories, the interstory drift time history and configuration of the formed nonlinear hinges. Moreover, the IDA curves corresponding to maximum interstory drift have been drown subjected to a number of near-field ground motions. The performance of studied structures was evaluated and compared.
