摘要:
采用统一强度理论对CFRP-方钢管混凝土轴压短柱进行受力分析，并引入等效应力系数、混凝土强度折减系数和等效约束折减系数，将CFRP-方钢管混凝土转化为CFRP-圆钢管混凝土，进而建立了CFRP-方钢管混凝土轴压短柱的极限承载力计算公式。将所得理论公式的计算结果与文献资料数据进行对比，验证了该公式的正确性，并进行了影响因素分析。结果表明：随材料拉压比、统一强度理论参数和CFRP厚度的增加，CFRP-方钢管混凝土轴压短柱的极限承载力不断增大，但CFRP的约束效率却随其厚度的增加在减小；所得结论可为CFRP-方钢管混凝土轴压短柱的设计、施工及推广提供一定的理论依据。
Abstract:
Based on the unified strength theory, the load carrying capacities of concrete-filled square CFRP-steel tubular stub column under axial compression were analyzed. The concretefilled square CFRP-steel tube was equivalent to concretefilled circular CFRP-steel tube through introducing equivalent stress factor, concrete strength reduction factor and equivalent constraint reduction factor. Then authors established a formula for calculating ultimate bearing capacity of concrete-filled square CFRP-steel tubular stub column under axial compression. Through comparing the results of proposed formula with those of reference data, the correctness of proposed formula was proved. The influencing factors of formula were also discussed. The results show that the ultimate bearing capacity of concrete-filled square CFRP-steel tubular stub column under axial compression increases with increasing the tension and compression ratio of material, unified strength theory parameter and thickness of CFRP. However, the confinement rate of CFRP decreases with increasing its thickness. The obtained results can provide some theoretical references for the design, construction and extension of concretefilled square CFRP-steel tubular stub column under axial compression.
