Taking a double-layer cylindrical reticulated shell as the research object, the seismic response characteristics of such structures are studied by means of dynamic time-history analysis. The influence of seismic wave input direction, horizontal restraint stiffness and different seismic waves on the seismic response of the structure are discussed. The comparison between the time-history analysis and the response spectrum method is made. Based on this, some suggestions for seismic design are proposed.
