摘要
以典型黄河铁路桥桥梁健康状况评估为目标,通过使用ABAQUS工程模拟有限元软件,在建立连续梁模型的基础上,从横向摇摆力作用下变形,以及应变和应力关系上进行桥梁状况模拟及分析,并在此基础上设计基于光纤光栅传感器的桥梁安全监测网络,为工程技术人员在铁路桥梁结构分析上提供了有效的方法。
To assessing the health of a typical railway bridge over the yellow river, the simulation and analysis of a single bridge condition under the swing forces from the horizontal by the ABAQUS finite element software using a continuous bridge model are presented in this paper. Based on the results, a fiber Bragg grating sensor network is designed to monitor bridge safety. An effective analysis method of railway bridge structure for engineers and technical is provided
