【摘要】 分析了一种闭口式压型钢板 混凝土组合楼板的构成特点和受力性能的同时 ,进行了 1 6块组合楼板的受弯试验研究 ,探讨了这种组合板的正截面抗弯承载力及其破坏形式 ,依据楼板的塑性截面设计理论给出了其承载力的简化计算公式。试验结果表明 ,这种组合楼板承载力高、延性好 ,具有较好的抗弯性能更多还原

【Abstract】 Based on the test of sixteen closed-section steel deck-concrete composite slabs,the bending-bearing capacities and collapse mechanisms are presented.Test results show that this type of closed-section composite slabs has both higher load-bearing capacity and good ductility.The design proposal and simplified formula for predicting the bending-bearing capacity are drawn.更多还原
