摘要
依据连续梁桥结构的特性,对其荷载试验进行快速分析。基于空间杆系有限元及结构动响应理论,结合桥梁荷载试验相关规定及要求,采用Matlab编制了结构静、动力分析、可变作用效应分析以及车辆自动布载程序,程序大大减少荷载试验方案设计的前期工作量,为连续梁桥荷载试验方案的制定提供参考。
According to the characteristics of continuous beam bridge structure, the rapid analysis on the load test is carried out. Based on the theory of finite element of spatial bar systemand structural dynamic response, in combination with the relevant provisions and requirements of bridge load test, the procedures of structural static and dynamic analysis, variable action effect analysis and automatic load distribution for vehicle are compiled by using Matlab. The procedure can greatly reduce the previous workload of the scheme design for load test, and provide reference for the formulation of the load test scheme for continuous beam bridge.
