Abstract |
Post-installed anchors were widely used due to its workable benefits. Regarding the resistance performance of anchors, the critical edge distanceis presented to minimize the impact of concrete splitting. In the case of actual anchors, however, it is difficult to obtain the ideal edge distance. Thepurpose of this study is to identify resistance performance and behavior characteristics that contain complex elements such as concrete crack occurringunder tensile load. Tensile tests were conducted based on the standard method. Failure shape and the resistance characteristics that do not have thecritical edge distance were derived by tensile load. Parametric analysis according to the boundary condition was performed to simulate the actual tensilebehavior, through a nonlinear finite element model based on the specimen. Consequently therefore, verifying analysis results the resistance mechanismcan be applied through boundary conditions.
