【 摘 要 】

In this paper, the principle of energy dissipation of anti-buckling support and the simulation method in finite element are introduced. A large-span steel truss deck type arch bridge with a large span is selected as the research object. Based on the analysis of seismic response characteristics, the anti-buckling restraint support is used to systematically study the damping control of long-span steel truss arch bridges. By comparing the seismic responses of the arch bridges before and after the anti-buckling support, the arrangement position of the anti-buckling support was optimized, and the damping effect of anti-buckling support was analyzed. The results show that the reasonable anti-buckling arrangement has better damping effect for long-span arch bridges, but the damping effect of anti-buckling support under different arrangements is quite different.
