【摘要】 地震等自然灾害可以直接破坏主体结构。主要构件的加固、修复成为令人关心的研究课题。研究了方柱在不同预压力下的混凝土应力-应变关系,测得了混凝土、CFRP约束混凝土和CFRP约束预压混凝土棱柱体在轴压作用下的应力、应变数值,进行了混凝土棱柱体在预压后用CFRP加固的再受荷强度影响分析,为实际工程的加固设计提供了试验依据。更多还原

【Abstract】 The earthquake damage of primary structure affects the application of building,therefore,strengthening and repairation of the stracture becomes and important research subject.The active concrete culumns with square section and confined by CFRP sheet were tested under uniaxial compression with different preloaded loading.The main aspects of the research work are experimental study of CFRP-confined prismatic concrete in service.The results give a reference to strengthening design of the structure.更多还原
