Generally, to determine different characteristics of two groups of far and near-field records, frequency content as well as long period pulse features in the velocity time history and great values of PGV and PGA parameters must be referred too. Major ground motions recorded during Tabas 1978 and Bam 2003 earthquakes in Iran are some of the best samples of strong and destructive wave-like motions containing a great deal of kinetic energy. Due to displaying pulse-like features in their velocity time history corresponding to the emergence of spike-shaped wavelets in their recorded ground acceleration, near-field records containing forward directivity effects are strongly capable of forcing huge kinetic energy on structures in a relatively short period of time. In this paper, the seismic behavior of a particular type of resistant structure called a rigid bundled tube under near-field ground motions is analyzed and studied. The studied skeleton is a ten-story rigid bundled tube with a value of mass eccentricity. The results are calculated and analyzed after conducting several nonlinear time history analyses under a number of three-component near-field records. Overall, the results of this research explain that seismic response parameters of asymmetric rigid bundled tube skeletons are not effectively sensitive to small amounts of mass eccentricity. Moreover, analytical assessments show larger amplitude for the seismic performance of plastic hinges in flexible edges of the plan compared to stiff edges. Finally, it is observed that rigid bundled tubes can satisfy the Iranian design code restrictions for story drift.
