DYNAMIC ANALYSIS OF FOLDED CANTILEVER SHEAR STRUCTURE AND BASE ISOLATED STRUCTURE

Seismic isolation is the most important in earthquake resistant structural design. Many isolation techniques have been developed to reduce the impact of earthquake. The seismic responses of eleven-storey models of folded cantilever shear structure as a proposed structure have been studied numerically. Folded cantilever shear structure (FCSS) consist of fixed-movable-fixed supported shear sub-frames and connection rigid sub -frame which connect their sub-frames at the top. The movable sub-frame is supported by roller bearings and additional viscous damper are attached laterally between beams
