中文摘要：
采用统一强度理论，对碳纤维布（CFRP）和角钢复合加固混凝土矩形柱的轴心受压机理和约束模型进行分析，考虑碳纤维布和角钢材料的特点及对混凝土的约束作用，提出了该复合加固混凝土矩形柱的轴心受压承载力计算公式．将本文计算公式与文献试验结果进行对比，验证了该理论公式的正确性，并进行参数分析，得出参数k及倒角半径等因素对承载力的影响规律．该结果为此类复合加固混凝土矩形柱轴心受压承载力的计算提供了一定的理论依据．
英文摘要：
Using the unified strength theory, the material characteristic of carbon fiber reinforced plastic（CFRP） and angel steel and their confinement to the concrete were taken into consideration, and the performing characteristics and confinement mechanism of the confined columns were studied. Based on the above analysis, the formulae for ultimate bearing capacity of rectangular concrete columns strengthened with both CFRP and angel steel were deduced. The comparisons between the calculation results and experi- ment results were made out and the results show that the theory formulae are correct and viable. The effects of the parameters k and comer radius are considered in the theoretic analysis. The results offer the theoretical foundation for the research of the rectan- gular concrete columns strengthened with both CFRP and angel steel.
