摘　　要：为研究实际工程中装配式钢骨增强微孔混凝土复合楼板的承载能力,通过静载试验,得到了其荷载-挠度曲线和裂缝长期发展特征,并对该复合楼板进行了配筋计算、裂缝宽度和挠度验算。此外,采用有限元软件MARC对复合楼板进行了受力分析,并与试验结果进行了对比,发现两者吻合程度较高。研究结果可为相关复合楼板的设计提供参考。In order to study the bearing capacity of prefabricated steel reinforced microporous concrete composite floor slabs in practical engineering,the loading-deflection relationship and the long-term crack development characteristics of the composite floor slabs were obtained by static loading test.The reinforcement calculation,crack width and deflection checking calculation were carried out.The finite element software MARC was used to analyze the stress state of the composite structure slabs,and the results were compared with the test results.The results show that the stress states of theoretical calculation and simulation analysis are quite consistent,which provides a reference for the design of composite structure slabs.
