某斜腿刚架拱桥静动载试验评估

针对斜腿刚架拱桥结构构造特点，对拱肋重要节点采用刚性连接方式建立了有限元模型，计算分析了设计活载及试验荷载作用下结构的静动载响应．同时，基于理论分析及现场静动载试验结果，分析和评估了该桥的承载能力及使用性能．有限元模型建立方法及静动载试验过程对该类桥梁性能评估具有工程借鉴意义．

Loading test of the rigid frame arch with inclined legs

This paper used the rigid-framed arch bridge with inclined leg structure of characteristics to establish finite element model in the arch rib important nodes use rigid connection, also the finite element model calculated live load and load test design under the action of static and dynamic structure in response. At the same time, based on the theoretical analysis results and the static and dynamic load test analysis and evaluation of bridge bearing capacity and performance. The finite element model establishment method and the static and dynamic load test for the bridge performance evaluation process has great significance to the project.
