摘要
以土城桥为工程背景，建立有限元模型对结构进行静力分析及动力特性分析，在满足强度、刚度及基频的条件下，研究人行桥各部分如何分段和连接，达到全拆装的目的。
Tucheng bridge as the engineering background, the finite element model is established to analyze the static analysis and dynamic characteristics of the structure, to meet the strength, stiffness and fundamental conditions, each part for the footbridge how to segment and connection was researched, to achieve the purpose of full disassembly.
