摘要
基于双剪统一强度理论 ,推导出钢管混凝土轴心受压承载力计算公式 .通过不同含钢率试件的轴心抗压试验 ,验证了理论公式的正确性 .与文献资料的试验结果比较 ,结论基本一致 .
Based on the twin shear unified strength theory, the analytical expression of the load capability is deduced when the concrete filled steel tube is suffered from axial compression.The correctness of the analytical expression is verified through the resisting compression tests of the axes having different steel ratio.The result of the paper is consistent with that of the test in the reference.The theoretical basic can be provided for the load capability analysis of concrete filled steel tubes by using the results of the paper.
