组合单向板加螺栓后正截面承载力计算公式的研究

The disquisition of calculation formulas of normal section bearing capacity of one-way composite slabs adding with bolts

通过对 18块刚特 5 5 0型压型钢板—混凝土组合单向板加螺栓后性能的破坏性试验研究 ,分析了组合板破坏特征 ,对组合板的正截面承载力进行了理论分析与计算。

Based on the analyses of 18 experimental specimens of one way composite slabs what were made of GT550 profiled steel with bolts and concrete under vertical load action,on the basis of failure character,the theoretical analyses and disquisition of normal section bearing capacity are proposed.
