Study on Seismic Response of Staggered Story Isolated Structure Under Ordinary and Long-Period Earthquake

PurposeStaggered story-isolated structures are widely used in various engineering applications. For such structures, earthquakes have different isolated performances under ordinary earthquakes and long-period earthquakes. Therefore, analyzing the staggered story isolated structures is necessary. A finite element model of a staggered story isolated structure was proposed to investigate their seismic response under ordinary earthquakes and long-period earthquakes to better understand and analyze its isolated performance.MethodsBased on related research, the structural finite element analysis software SAP2000 was used in staggered story isolated structures. The responses of the structures under ordinary earthquakes and long-period earthquakes were compared.ConclusionA nonlinear time-history response was obtained to evaluate the seismic response of staggered story isolated structures using various parameters. Different earthquakes have different effects on structures, which should be considered in the design.
