| 摘 要： | 在碳纤维板不同的嵌贴长度、嵌贴数量、开槽净间距、混凝土强度及配筋率作为试验因子的条件下,对8根矩形截面梁进行单调加载试验,研究不同加固条件对加固梁的破坏形态、刚度变化、裂缝开展情况及极限承载力的影响。试验结果表明:这些加固措施有效地提高了梁的抗弯极限承载力和刚度,较好地约来了裂缝的发展。

| Abstract: | It is described loading tests on rectangular cross section of RC beams under conditions of carbon fiber-reinforced polymer sheets' different bonded lengths and amounts,clear spacing of notch,intensities of RC and ratios of reinforcement as parameters.And the purpose of these tests is to study the distinct effects of these strengthening conditions on the strengthened RC beams' failure mode, change in stiffness,crack spread situation and ultimate bearing capacity.The experimental results show that the flexura... |
