EVALUATION OF RESPONSE OF MULTI-STOREY STRUCTURE THROUGH NON-LINEAR ANALYSIS USING STRUCTURAL FUSES

Abstract

Research and development of passive energy dissipation devices for structural applications have roughly a 25-year history. The basic function of passive energy dissipation devices when incorporated into the superstructure of a building is to absorb or consume a portion of the input energy. The passive energy dissipation devices that are chosen for investigation include metallic bracings which are used as structural fuses. Structural fuses are supplemental energy dissipating devices that are fabricated into the structure to ensure safety of primary structural members. They are installed in the second and third bay of building. Three different type of bracing(X,V,IV) and Xplate metallic damper are used. The analysis is carrying out for modeled 8storey building by ETAB-2016 software and designed according to IS1893:2002 code specification. The static pushover analysis is carried out. Interstorey drift, storey displacement, shear force and moment proved to be the key constraints in accessing the performance of the building structure.
