Abstract
A T-stub with a thin flange and a wider high-strength bolt gauge distance generally fails due to the yield of the flange. Since prying action greatly influences a T-stub with such failure characteristics, its effects must be considered in estimating the failure aspects, stiffness, and strength of a T-stub. To accurately determine the effects of a prying action applied to a T-stub and to reflect them in a design, however, the contacts, bearing, concentrated stress, and plastic hinges, among complex submaterials, should first be accurately examined and quantified. Thus, this study aimed to explain better the complex phenomena that influence the effects of prying action by conducting an axial tensile force test and a three-dimensional nonlinear finite element analysis of a T-stub and proposing an improved analytical model for estimating the initial axial tensile stiffness and the ultimate tensile load of a T-stub, including the effects of prying action on it.
