RESILIENT SLIP FRICTION JOINT FOR STEEL MOMENT RESISTING BRACED FRAME

Recent studies shows that major earthquakes has end up in the severe damage of the structure, which led engineers in find of techniques which not only provide people’s safety, but also aspire to cutdown damages in the structures. In this article, a single bay, ten-story concentric braced frame with non-buckling bracing is developed to study the energy dissipation. Particularly this evaluation is done to check their stability after earthquake loadings. Traditional lateral force resisting systems include moment resistant frames and frames that are concentrically braced. This Traditional lateral force resisting systems is in use for long period of time, but the result obtained from these methods is average level. The insufficient stiffness of moment-resisting frames and the inadequate ductility of concentrically braced frames have propelled significant research efforts toward the advancement of novel lateral resisting systems that include more stable hysteretic behavior, suitable ductility, control of damage, and energy dissipation capability. Conventional Moment Resisting Frames (MRFs) become softer and as a result energy dissipates in higher amount under seismic design analysis. There is a linked damage in important areas of the key structural members as a result of the earlier complaints. This collision could cause serious damage and long-lasting tremor following the earthquake. To prevent the drift, a self-centering damage evasion initiative known as Resilient Slip Friction Joint (RSFJ) was created for steel Moment resisting Frame. The RSFJ achieves both the behavior of self centering and the task of energy dissipation, there-by resulting in seismic resistance. Added to that, an innovative energy dissipater, present inside the RSFJ as the central fuse, supports the building. Self-centering friction-dampening brace members, as opposed to conventional brace members, make the greatest use of the available characteristics in steel structures with concentrically braced frames. This results in minimising residual deformation and withstand earthquake load without replacing any of the member. The present research compares the performance of momentresisting braced frames with and without RSFJ dampers during seismic activity. The purpose of this research is to determine whether RSFJ dampers for steel moment resisting brace systems are a good replacement for the current standard bracing systems with dampers and give performance advantages
