| 摘 要： | 为研究肢长比对偏压下CFRP布加固钢筋混凝土L形截面柱的力学性能影响规律,对不同肢长比的构件进行ABAQUS数值模拟。将得到的试验参数进行分析,结果表明:随着肢长比的增大,极限承载力下降;肢长比越大,其受拉区CFRP布、钢筋两者的抗拉特性发挥得越充分,CFRP布对承载力提高的幅度越大,所以CFRP布对肢长比较大的钢筋混凝土L形柱的加固效果较明显。

| Abstract: | In order to study the effect of limb length ratio on the mechanical properties of Reinforced Concrete L-shaped Columns Strengthened with CFRP cloth,numerical simulation of ABAQUS with different limb length ratio is carried out. The obtained test parameters are analyzed,and the result shows:with the increase of limb length ratio,the ultimate bearing capacity decreases;the reinforcing effect of CFRP cloth on L-shaped reinforced concrete columns with larger limbs is obvious. The larger the ratio of the limb length,the larger the bearing capacity is. The tensile properties of both CFRP cloth and steel bar in the tension zone also play a full role. |
