基于动力荷载试验的某斜拉桥动力性能评估

Structural monitoring and assessment for a cable-stayed bridge based on dynamic test

本文介绍了桥梁结构动力荷载试验的内容、试验方法及试验原理。并通过空间梁格系有限元技术对某斜拉桥进行有限元理论分析和成桥试验,分析了该桥的使用性能和效果。

This paper introduces the test content and method and theory about bridge structure dynamic load,analyze usability and effect of this bridge with the method of analyzing certain cable-stayed bridge by finite element theory and testing the bridge-completion through the finite elements technology of space beam grillage.
