制作两个不同含钢率的轻钢EPS混凝土新型组合楼板试件，研究含钢率对其抗弯承载力的影响。试验采用两端简支静力加载方式进行，测量试件的变形及钢骨架的应力状态，确定试件的破坏极限状态。通过试验观察和分析，明确轻钢EPS混凝土新型组合楼板的破坏形式为弯曲破坏，破坏主要发生在纯弯段内，试件没有发生突然破坏现象，表明新型组合楼板具有较好的延性，且随着新型组合楼板含钢率增大，试件的承载力增加。同时，采用有限元方法分析了新型组合板的变形性能，分析结果与试验结果非常吻合，该研究结论可为完善轻钢EPS混凝土组合结构的设计提供理论基础。

Two light steel EPS concrete composite floor slab specimens with different steel ratios were made, and the influence of steel ratio on the flexural bearing capacity was studied. The test was conducted using a static loading test with both ends simply supported. The deformation and stress state of the steel frame were measured, and the ultimate limit state of the specimens was determined. Through observation and analysis of the test, it was found that the failure mode of the light steel EPS concrete composite floor slab was bending failure, and the failure mainly occurred in the pure bending section. The specimens did not show sudden failure, indicating that the new composite slab has good ductility. At the same time, the finite element method was used to analyze the deformation performance of the new composite slab, and the analysis results were very consistent with the test results. The research conclusions can provide theoretical basis for improving the design of light steel EPS concrete composite structures.
