Over the past decades, earthquake resistant design of building structures has been largely based on ductility design concept worldwide. The performance of the intended ductile structures during major earthquakes (e. g. Northridge, 1994; Kobe, 1995; Chi-Chi, 1999etc) however have proven to be unsatisfactory and indeed far below expectation. So, performance based seismic design philosophies in seismic design has become the cardinal point of interest in civil engineering structures Due to the vulnerability of Bangladesh to earthquake, dynamic analysis should be introduced in major earthquake zone to ensure the seismic performance. To see the dynamic behavior of the structure, dynamic analysis should be performed for building with varying height. Dynamic analysis can take the form of a dynamic time history analysis or a linear response spectrum analysis. In this present study, a building of 15 stories with varying floor height has been modeled using software packages SAP2000 v15 for seismic zone of Bangladesh. Dynamic response of building under actual earthquakes, chi-chi, Taiwan, 1999, El centro and Northridge have been investigated. This paper highlights the effect of varying height in high-rise building with Time History Analysis.
