BENDING TESTS AND NUMERICAL ANALYSIS OF CFRP STRENGTHENED RC BEAMS

摘要: 对6根碳纤维布加固的钢筋混凝土梁进行受弯性能试验研究。试验结果表明,在一定的条件下,用玻璃纤维布U型箍替换部分碳纤维布U型箍,其加固效果差异不大,但却可以有效地降低加固成本,其试验结果对工程实际有一定的参考价值。利用ANSYS有限元分析软件对碳纤维布加固钢筋混凝土梁的非线性问题进行仿真模拟,结果与试验值较为接近,差值在10%以内,可在一定程度上代替试验分析。Abstract: It is conducted an experimental study on the flexural performance of 6 CFRP strengthened RC beams.Test results show that under certain conditions,when substituting GFRP U-hoops for partial CFRP U-hoops,the reinforcement effect will be about the same,but it can effectively reduce the cost of reinforcement,the test results provide a reference for engineering practice.CFRP reinforced concrete beams nonlinear problems can be simulated by ANSYS,the results are closer to those of the test,i.e.a difference is in 10%,hence to some extent,it can substitute for test analysis.
