摘要
本文使用有限元分析软件ABAQUS对BFRP布加固钢筋混凝土梁进行受力性能分析,用壳单元来模拟BFRP布粘贴于梁底部,采用BFRP布与梁底粘结长度作为变量,分析梁的开裂荷载、挠度变化的影响。模拟结果表明粘结长度对梁底界面开裂的荷载影响不大,对挠度有一定的降低作用。
In this paper, finite element analysis software ABAQUS is used to analyze the mechanical properties of reinforced concrete beam reinforced by BFRP , a shell element is used to simulate the BFRP cloth sticking to the bottom of the beam , the bond length between BFRP cloth and beam bottom was taken as the variable , analyzing the cracking load , the deflection of the beam. The simulation results show that the bond length has little influence on the load of the cracks at the bottom of the beam , and it can reduce the deflection.
