This paper is a summary of an attempt to provide a phenomenological model in order to capture the nonlinear behavior of bracing members. The result obtained from modeling of a bracing system with the aid of the phenomenological model is compared with the result of a test to investigate the accuracy of the investigated model. Furthermore, static non-linear analyses are performed on an inverted V-braced subassembly using the phenomenological model as well as a convenient physical theory model. According to this study, the proposed phenomenological model is capable to favorably capture the behavior of a brace member under a cyclic loading. Hence, it can be used in analytical models of structural lateral bracing systems to assess accurately the nonlinear behavior of these systems.
