摘要：
As an effective base isolation device, friction pendulum bearings (FPB) were finely modeled and applied in the K8 single-layer reticulated domes in this paper. First, influence of friction pendulum bearings was analyzed on the seismic performance of single-layer spherical reticulated shell from two aspects, the peak acceleration and earthquake energy. Moreover, the seismic performance of structure with FPB was studied under different ground motion intensities from three aspects, the dynamic stress, the nodal acceleration, and the vertical relative displacement of nodes. The result showed that the peak vertical acceleration was reduced and a part of earthquake energy was isolated by using FPBs. Under the different ground motion intensities, the seismic effect of a K8 single-layer spherical reticulated shell structure with FPB was similar.
