摘要
为探讨CFRP加固轴心受压混凝土方柱的承载力计算方法,将其受力截面分为强约束区和弱约束区,承载力计算简化为2个阶段,并提出了计算公式及其适用条件;与试验结果对比,吻合较好.证明使用该方法对CFRP加固混凝土方柱的受力进行分析,简化了计算过程是合理有效的.
In order to discuss the calculation method of bearing capacity of axial compressed concrete column reinforced with CFRP, its section is divided into two parts, i. e, strongly restricting region and the weakly restricting one. The calculation of bearing capacity is simplified to two stages, in which the corresponding calculation formula and applicable conditions are propounded. By contrasting with the testing resuits, the calculating results are agreeable with the testing one, which indicates that using this method to analyze the stress of concrete column reinforced with CFRP is reasonable and effective, and it simplifies the calculating process.
