摘要 推导了CFRP界限加固截面积计算公式,建立了RC梁CFRP加固截面积优化数学模型,并确定了其限制条件,利用MATLAB的优化工具箱编制计算程序对CFRP的最优化截面积及对应的最大极限破坏承载力求解。并特制了4根CFRP加固RC梁,理论计算值得到了弯曲静载试验测量值的验证。 The calculating method of strengthened CFRP area was deduced, and the optimization model of strengthened CFRP area for RC beams was built and the confinement conditions was determined. The optimized CFRP area and the corresponding ultimate bearing force was solved with the computational program compiled by optimum toolbox in MATLAB. 4 CFRP strengthened RC beams were fabricated and the theoretical calculated value has been proved by the measured results of the flexural tests.
