摘要通过12根加固钢筋混凝土方柱的轴心受压试验和有限元分析的结果,确定了碳纤维布约束混凝土方柱在轴心受压作用下的计算模型,并提出两种碳纤维布约束混凝土方柱的承载力计算方法,两种方法的计算结果与试验结果吻合的较好,研究结果可供工程应用参考。 12 square concrete columns confined with Carbon Fiber Reinforced Plastic (CFRP) under axial compression were tested. Finite element analysis was performed and a calculating model was presented to predict the ultimate strength of square Concrete Columns Confined with Carbon Fiber Reinforced Plastic. Two methods for calculating bearing capacity of CFRP-confined columns were put forward. The results of both methods are in good agreement with the experimental data. The results can serve as reference to engineering application.
