AN ANALYTICAL STUDY ON DETERMINING THE FUNCTIONAL POTENTIALITY OF NON MOMENT RESISTING BRACED FRAMES TO MINIMIZE EARTHQUAKE INDUCED DAMAGE

Abstract: In this research article, an analytical study on determining the functional potentiality of non moment resisting braced frames to minimize earthquake induced damage has been presented. A self-centering damage avoidance idea called a Resilient Slip Friction Joint (RSFJ) was created for steel Moment Resisting Frames employing a unique Resilient Slip Friction Joint (RSFJ). The RSFJs make it possible for a gap to open up in the connection during loading, and they re-center the system when loading has been completed. An analytical model was constructed in order to precisely anticipate the behaviour of this system in terms of its moment-rotation relationship. A single-bay ten-storey concentric braced frame with diagonal Non-Buckling bracing is chosen for studying their effect during earthquake loadings. This study aims to analytically obtain the seismic performance of non-moment resisting braced frames with and without RSFJ dampers. The frames were modelled and designed in ETabs software and a pushover analysis & time history analysis was performed.
