摘要:Abstract: Rubber isolation technology is an effective means to mitigate the dynamic responses of a building under seismic excitations, now it has been applied widely in engineering, from those lower stiff buildings to some complicated structures, such as large scale irregular stadium, bridges, and even high rise buildings recently. Such trends lead to higher requirements for dynamics response ana- lysis, especially for those larger scale structure, the arisen key problem is how to simulate the nonlinear hysteresis property of the rubber bearing, and incorporate the programs in the finite element analysis. Based on the secondary development platform of ABAQUS, we program for the rubber bearing element, in which, the Bouc-Wen model is employed to describe the hysteresis be- havior in lateral, while the strength-differences of vertical stiffness are treated as well. An iregular building is simulated to investigate the effects of base isolation by using the developed program.
