| 摘 要： | 将摩擦摆(FPS)引入到网壳结构的隔震控制中。文中首先阐明了FPS的工作机理和本构关系,建立了FPS隔震网壳结构的振动方程。通过双层球面网壳结构的数值算例考察了隔震和无控结构在单向和三向地震作用下的振动响应以及FPS的控制效果。研究结果表明,FPS具有良好的隔震和耗能效果,可有效地应用于球面网壳结构的振动控制。

| Abstract: | The application of friction pendulum system(FPS) to seismic isolation of lattice shell structures is presented.Theoretical model of the FPS is first introduced.Motion equations of the lattice shell with FPS bearings are established.Then,seismic isolation studies are performed for double-layer spherical lattice shell structures subjected to both single and three-component seismic excitations.Meantime,seismic isolation performance of the FPS is investigated under different earthquake inputs.The results show t... |
