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 develop the research on structural behaviors and real loading carrying capacities of steel-concrete bridge deck slabs with compressive membrane action, static test was constructed on a series of one to third scaled bridge models. The influence of compressive membrane action on ultimate strengths was studied with varying structural parameters including concrete compressive strength, reinforcement percentages and the size of steel supporting beams. By the comparison of the experimental test results with current design codes and numerical model, it was found that current standards highly underestimated the real strengths of bridge decks and numerical analysis showed a good correlation with experimental results.
