Seismic Design and Reinforcement Method of Long-Span Supension Bridge
A suspension bridge is a bridge formed between a beam bridge and an arch bridge,which has advanced terrain conditions such as crossing valleys,rivers and bays.The seismic design of a suspension bridge is to study the structural response of the suspension bridge under seismic action and propose seismic design schemes based on three aspects:increasing the key components,structural form,and adjusting the damping ratio.Based on the seismic response analysis results,the seismic performance of the suspension bridge was evaluated.Besides,the measurement of reducing and seismic isolation and the reinforcement methods of the suspension bridge were proposed.
