000019779 520__ $$2eng$$aThe behavior of X-braces in steel buildings depends on various parameters such as slenderness ratio of diagonals, details of gusset plates, middle connection and stitches configurations, material properties, beam to column connection and etc. Some innovative details used in three half-scale tests to verify different aspects of this system. The application of Lower-Grade Steel for design of braces implemented to absorb earthquake energy. In addition, Parallel stiffeners used inside diagonals in one of specimens to dissipate earthquake energy by accordion behavior. This test was repeated by oblique diagonals and analogous results presented. In addition, a new configuration introduced instead of conventional central plates at middle of diagonals to decrease the effective length factor of braces and increase the braces capacity in compression. Brief demonstrations of specimens and failure modes during experimental cyclic tests presented and the critical seismic parameters compared and discussed. According to tested specimens, the considerable effects of proposed details and theories in energy dissipation capacity improvement of this system clarified.
