Abstract

Long-span latticed shell structures are widely used in public buildings such as stadiums and transportation hubs due to their advantages of light weight, high strength, and flexible spatial forms. However, their complex response characteristics under dynamic loads such as earthquakes pose significant seismic safety hazards. To investigate the shock absorption effect of the proposed U-shaped composite damper and reduce the seismic response of latticed shell structures, a U-shaped rubber composite bearing (formed by combining the U-shaped composite damper with a lead-zinc rubber bearing) was applied to the latticed shell structure for nonlinear dynamic time-history analysis.

Keywords
