摘要
为检验某钢桁腹预应力混凝土组合梁桥的承载能力是否满足正常使用状况的要求,对该桥在静载作用下的挠度、应力进行试验分析。研究结果表明,该桥的受力性能和正常使用状态极限承载力均满足设计要求,结构工作状况良好。
In order to study the carrying capacity of a steel truss web and concrete composite box-girder bridge, this paper tested and analyzed deflection and stress under static load.The results showed that mechanical behavior and ultimate bearing capacity of the bridge under normal service condition could meet design requirements, and the structure was in good working condition.
