In this paper, the cyclic nonlinear behavior of a brace element has been modeled. A brace element is modeled as two elastic beam-column segments, which are connected to each other via a plastic hinge. The far ends of the element are hinged. By a suitable combination of the isotropic and kinematical hardening rules of plasticity, the nonlinear axial force-displacement relation for a beam element has been derived. So, the strain hardening, strain softening, tangential modulus of elasticity and Bauschinger e ects are taken into account. This model shows good agreement with experimental results that have been reported in other research works.}, keywords = {Bracing,Nonlinear,Work hardening}, url = {https://scientiairanica.sharif.edu/article_3176.html}, eprint = {https://scientiairanica.sharif.edu/article_3176_2a55c2aecdd2026d2fb489a1456449ea.pdf} }
