摘要:

为了研究纤维增强复合材料(FRP)加固后砖砌体的抗剪承载力,对1片未加固带壁柱墙体及8片FRP加固的带壁柱墙体进行了抗震性能试验; 在FRP与砖界面黏结-滑移本构关系基础上,考虑FRP与墙体的界面剥离,将界面黏结力转化为桁架模型中的拉力,并考虑FRP的直接加固作用与间接加固作用,建立了FRP加固砖砌体抗剪承载力的理论计算模型。结果表明:该模型所得结果与试验结果及其他研究结果吻合较好,且可以很好地计算FRP加固后砖砌体的抗剪承载力。

Abstract:

In order to study the shear capacity of brick masonry strengthened by fiber reinforced polymer(FRP), the seismic performance tests of one piece of normal masonry wall and eight pieces of brick masonry walls strengthened by FRP were carried out. Based on the bond and slip constitutive relation of FRP and brick interface, the influence of interfacial debonding of FRP was taken into account, and the interfacial adhesion to tension of truss bar model was transformed, meanwhile, the direct and indirect reinforcement effects of FRP were considered. Finally, the theoretical calculation model of shear capacity for brick masonry strengthened by FRP was established. Results show that it has an excellent coincidence with the experimental results which is derived from the test, and the shear capacity for brick masonry strengthened by FRP can be well calculated by using the model.
