CFRP 加固结构中框架梁有限元分析

摘要

In order to research the influence of performance on RC structure strengthened by CFRP,non-linear analysis is performed on RC frame beams by ANSYS. Research on the mechanical performance of RC frame beams with a rectangle cut is being performed before or after strengthe-ning. The result can be summarized as follows:the mechanical performance of RC frame beams strengthened by CFRP is greatly improved,and the function of the CFRP is used fully.%为了研究 CFRP（碳纤维复合材料）对于结构性能的影响，采用 ANSYS 有限元分析软件对加固工程中的 RC 框架梁进行了非线性分析，研究了 RC 矩形截面框架梁在 CFRP 加固前后的力学性能，研究结果表明：CFRP 加固后的框架梁的力学性能明显提高，CFRP 充分发挥了作用。
