摘要
利用ANSYS对混凝土梁的三种不同加固方法进行有限元分析,对加固前后梁的非线性性能、正截面受弯承载力、挠度变化进行了分析研究。结果表明:混凝土梁破坏时碳纤维加固梁的挠度最大,钢板加固梁的挠度最小,而碳纤维复合钢板加固梁则居于两者之间,三种加固梁的受弯承载力都有较大的提高。
In the paper,finite element analysis of three different strengthening methods for RC beam are made with ANSYS;the nonlinear property,bearing capacity of bending at the normal section,deflection variation of the beam before and after strengthening are analytically studied.The result indicates that the failed RC beam strengthened by carbon fiber has the maximum deflection value,that strengthened by steel sheet has the minimum deflection value while that strengthened by CFRSS has the deflection value in between;and it also suggests that the bearing capacity of bending of the RC beam can be improved considerably by any of the three methods.
