| 摘 要： | 针对组合楼板主要的破坏模式——纵向剪切破坏进行分析,对8块U76型压型钢板-混凝土组合楼板进行了静力试验。试验结果表明:组合板越厚、剪跨越小、剪力横向钢筋越多,组合板纵向受剪承载力就越高。通过与无栓钉组合板的试验结果比较分析,表明组合板中剪跨区的栓钉,能极大地提高受剪承载力;并通过试验得到组合板的荷载-纵向相对滑移关系曲线图,采用欧洲规范4的建议公式,以试验数据为依据,回归得出组合楼板的剪力粘结系数m、k,为该种楼板的工程设计提供参考依据。

| Abstract: | In order to study the longitudinal shear capacity of composite slabs,static loading tests for eight U76 cold formed steel deck——concrete composite slabs were conducted.The Test result showed that shear capacity is higher for the thicker composite slabs,the smaller shear span,the more distributed reinforcing bar in the composite slabs.By comparing with the result of composite slab without studs,the findings showed that the studs in shear span can strengthen the shear capacity most effectively.Also based on test results of longitudinal slide and load relationships,shearing bond coefficients m and k of formula suggested by Eurocode4 were defined with regression analysis,which can be used in practical design. |
