大跨桥梁地震响应分析研究

Seismic Response Analysis of Long-span Bridges

从某大跨桥梁入手,分析大跨桥梁结构在不同等级地震作用下的结构响应,得出:顺桥方向地震作用下震动较为严重但不是优先发生破坏的方向,垂直于顺桥方向地震时侧移较大,为优先发生破坏的方向,在进行桥梁设计及施工时应引起重视.

This paper starts with a long span bridge. The structural response of long-span bridge structuresunder different earthquake levels is analyzed. It is concluded that the earthquake motion under the directionof the bridge direction is more serious but it is not the direction of the destruction. Horizontal displacementof bridge under earthquake is bigger. It is the direction of destruction. Attention should be paidto the design and construction of the bridge.
