Seismic Isolation Analysis of SMArubber Bearings in a Singlelayer Spherical
Lattice Shell Structure/Zhuang Peng1, Xue Suduo1, Li Binshuang1,2（1 The College of Architecture and Civil Engineering, Beijing University of Technology, Beijing 100022, China; 2 Beijing General Municipal Engineering Design and Research Institute, Beijing 100045, China）
Abstract:The dynamic analysis of seismically isolated singlelayer spherical lat
tice shell structures by a new type of SMArubber bearing is performed systemat
ically. The theoretical method and the corresponding computing program are devel
oped. The numerical simulations of different analysis cases of a Kiewitt single
layer spherical lattice shell under earthquake action show that such new seism
ic isolation bearings can be used to reduce the structural responses effectively.
Keywords:SMArubber bearing; singlelayer spherical lattice shell; seismic isolation;
vibration control
