    Abstract
    This research evaluates the inelastic behavior of ductile Buckling-Restrained Braced Truss-girder Moment Frames (BRBTMF) by analytical means. The BRBTMF proposed in this paper is the modification of the Special Truss Moment Frames (STMF) Vierendeel type by inserting Buckling-Restraint Braces (BRB) inverted-V-type into Vierendeelsegment to improve its inelastic behavior. The BRB section is a strip plate core LYS235 low yield steel, cased with rectangular hollow section A36 steel as a buckling-restraint material. The four story-seven bays frame model is analyzed using DRAIN-2DX nonlinear software. From the Nonlinear History Analysis using earthquake records, it can be concluded that in general, the BRBTMF has better inelastic behavior than the STMF Vierendeel type. The BRBTMF has the drift ratio up to 40.5 percent and the roof displacement up to 20.2 percent less than those in the STMF Vierendeel type due to the Miyagi record. It has been proven from the Nonlinear Static Push-Over Analysis that the BRBTMF has a good ductility, which is 33.2 percent greater than that of the STMF Vierendeel type. The base shear resulting from the Push-Over Analysis in the BRBTMF is 41.4 percent less than that in the STMF Vierendeel type. Based on these preliminary studies, it is possible to verify the validity of the BRBTMF proposed by experimental means and furthemore the BRBTMF may be implemented to practice.
