浙南某木拱廊桥的力学特性分析
|
摘要
以浙南泰顺地区的某座木拱廊桥为研究对象,通过有限元软件MIDAS建模仿真,对典型木拱廊桥进行静力特性分析和地震时程分析,探讨了静力荷载下拱架受力最大位置和动力荷载下的振型、基频等动力特性。
A finite element model of one wooden arch bridge in southern Zhejiang Province was established with MIDAS to analyze the static characteristic and seismic response under earthquake. According to the results, basic frequency and mode parameters of vibration were recognized. The static force analysis results also showed that which part of the arch structure was under the largest stress.
