| Abstract: | This investigation is concerned with the analytical theories and computational methods of seismic response for single layer spherical lattice shells. Based on the results of K8 single layer spherical lattice shells, seismic responses of single layer lattice shells under vertical and horizontal earthquake excitations are obtained. Furthermore, effects of major structural parameters, such as the geometrical parameters, the rigidity of supports and damping ratios, on the dynamic behavior of single layer spherical lattice shells are investigated in detail. The obtained results are valuable for the design of single layer lattice shells in seismic regions. |
