摘要
提出了SMA拉索-复摩擦摆支座(SMA cable-double friction pendulum bearing,SCDFPB),考察了其在三层Benchmark钢框架结构中的隔震控制性能。首先,给出了SCDFPB的构造,并提出了相应理论模型,并基于有限元模拟方法对上述设计进行研究,掌握其力学性能情况。然后,将此新型隔震支座引入到Benchmark钢框架结构中,基于OpenSees对结构进行了抗震动力时程分析,评估了隔震和非隔震钢框架结构的抗震性能。研究表明,与非隔震结构相比,SCDFPB隔震结构在水平双方向上减震效果明显,验证了此新型隔震支座有助于改善钢框架结构的抗震性能。
A SMA cable-double friction pendulum bearing(SCDFPB)was proposed,and its seismic isolation control performance in a three-story Benchmark steel frame structure was investigated.First,the structural design and theoretical model of SCDFPB were given,and then its mechanical properties were studied using finite element simulation method.Subsequently,this new type of isolation bearing was introduced into the Benchmark steel frame structure,and behavior the seismic time history analysis of the structure was carried out based on OpenSees,platform the seismic behavior of the isolatied and non-isolatied steel frame structure was compared and evaluated..The research results show that compared with the non-isolated structure,the SCDFPB-isolated structure satisfactory isolation effect in the horizontal directions compared with the non-isolated structure.This indicates that the seismic performance of steel frame structures can be improved using the SCDFPB system.
