摘要:
采用双剪统一强度理论,综合考虑方形薄壁钢管的局部屈曲效应以及轻骨料混凝土与普通混凝土多轴强度准则差异的影响,推导出了方形薄壁钢管轻骨料混凝土轴压短柱的极限承载力计算公式,同时分析了拉压比、材料强度参数、宽厚比和混凝土强度对极限承载力的影响。结果表明:该计算结果与文献试验结果吻合良好,验证了公式的合理性; 该结果为方形薄壁钢管轻骨料混凝土轴压短柱的承载力分析计算提供了理论依据,具有工程参考价值。
Abstract:
Based on the twin shear unified strength theory, considering the effects of local buckling of the square thin-walled steel tube and the multi-axial strength criterion for lightweight aggregate concrete, the calculation formulae of ultimate bearing capacity of short column of lightweight aggregate concrete filled square thin-walled steel tube were deduced, meanwhile, the influences of tension-compression strength ratio, material strength parameter, width-thickness ratio, as well as concrete strength on the ultimate bearing capacity were analyzed. Results show that the calculated results obtained in the paper agree well with test results from the references, and it can verify the rationality of the formulae. It can provide the theoretical basis for calculating the bearing capacity of short column of lightweight aggregate concrete filled square thin-walled steel tube, and this solution has an important practical value for engineering applications.
