摘要:
对长安大学人行天桥进行静、动载试验检测,基于结构损伤识别和承载力评定原理建立了桥梁的有限元数值分析模型,针对该人行天桥的结构特点、结构外观检查结果和使用现状设计了静、动载试验检测方案。对现场静、动载试验数据和数值模拟结果进行了对比,并对该类桥梁结构的承载力与安全性评估、健康检测及损伤诊断过程进行了具体的分析和介绍; 对结构性能和使用状态进行了综合评价,并根据其结构损伤和病害特点进一步提出养护方案。结果表明,该桥虽受力状况复杂,但使用状况基本完好。
Abstract:
A static and dynamic load test examination for Chang'an University Pedestrian Bridge was carried out. In view of the structural characteristic of pedestrian bridge and the result of appearance examination, the finite element simulation analysis model for the pedestrian bridge was established based on structural damage detection and bearing capacity evaluation theory, and the test examination scheme of static and dynamic load was designed. Meanwhile, the bearing capacity and security evaluation, the health examination as well as the damage diagnosis process for this kind of bridge were analyzed and introduced through the condition visual inspection, and the result contrast analysis between the static and dynamic load empirical datum with the numerical simulation ones was done. After providing the synthesis evaluation for its structure performance and the running condition, the further proposed maintaining scheme was given in terms of structural damage and disease characteristics. The results show that the bridge behavior is in good condition although its stress status is complicated.
