SMA-橡胶支座在单层球面网壳结构中的隔震分析
Seismic Isolation Analysis of SMA-rubber Bearings in a Single-layer Spherical Lattice Shell Structure
【摘要】 对新型SMA-橡胶支座隔震单层球面网壳结构进行了系统的动力分析。给出了理论分析方法,编制了相应的计算程序。对某凯威特单层球面网壳在不同工况下地震响应的数值模拟表明,该新型隔震支座可有效降低空间网壳结构的振动响应。
【Abstract】 The dynamic analysis of seismically isolated single-layer spherical lattice shell structures by a new type of SMA-rubber bearing is performed systematically.The theoretical method and the corresponding computing program are developed.The numerical simulations of different analysis cases of a Kiewitt single-layer spherical lattice shell under earthquake action show that such new seismic isolation bearings can be used to reduce the structural responses effectively.
