为了研究钢混桥梁面板在压缩薄膜效应作用下的结构性能和真实承载能力,进行了一组1∶3比例桥梁模型的静力加载试验;并通过对混凝土强度、配筋率和支撑梁尺寸的改变来分析压缩薄膜效应对结构承载能力的影响。将试验结果与现行规范计算结果和数值模拟结果进行比较后发现,现行的设计方法不能够准确地反映桥梁面板的真实承载能力,而数值分析结果与试验结果有着较好的吻合。
In order to study the structural performance and real load bearing capacity of steel-reinforced bridge deck under the effect of compression film, a set of 1: 3 ratio bridge model static load test was carried out. Through the analysis of concrete strength, reinforcement ratio and support beam size Changes to analyze the effect of compression film on the structural load-bearing capacity. Comparing the test results with the current normative calculation results and the numerical simulation results, it is found that the current design method can not accurately reflect the real carrying capacity of the bridge panel, and the numerical analysis results are in good agreement with the test results.
