单钢板-混凝土组合板承载性能分析

为研究单钢板-混凝土组合板在公路桥梁中的应用，提出一种新的钢板与混凝土板组合形式。通过对其进行仿真模拟结合静力试验，研究其裂缝发展模式和破坏形态，分析该模式组合板受弯承载性能。试验结果表明：试件破坏模式为弯剪混合破坏，在试验过程中，试件截面纵向应变沿组合板高度上基本符合平截面假定，在破坏前有明显的变形特征，且承载性能较好。可见该形式的组合板基本能满足使用需求，对实际工程组合板的选型有一定的参考意义。

Analysis of Load-bearing Performanceof Single Steel Plate Concrete Composite Slab

In order to study the application of single steel plate and concrete composite slab in highway bridge, a new composite form of steel plate and concrete slab is proposed . Through simulation and static test, the crack development mode and failure mode of the composite slab are studied, and the bending bearing performance of the composite slab is analyzed. The test results show that the failure mode of the specimen is flexural shear mixed failure. In the course of the test, the longitudinal strain of the specimen section is basically consistent with the assumption of flat section along the height of the composite plate, and it has obvious deformation characteristics before failure, and the bearing performance is good. It can be seen that this form of composite board can basically meet the needs of use, and has certain reference significance for the selection of actual engineering composite board.
