Abstract

Building structures of apartment in korea conventionally adopt shear walls using coupling beams as seismic force-resisting systems. Energydissipating devices employed the building structures are used instead of the coupling beams in order to increase the seismic performances by providingadditional damping and stiffness. This study aims to introduce energy dissipating devices which are preferred in structural system and aims to investigatestructural behaviors of shear wall structures employing such devices instead of coupling beams. In order for achieve research objectives, Finite ElementAnalysis and Nonlinear analysis was carry out. Finite Element Analysis results was correspond with experimental results and this is indicated that thedevice can provide sufficient additional damping and stiffness into shear wall structures. Throughout nonlinear static analyses, examples structureswith the devices can enhance seismic performance of building structures due to their sufficient energy dissipating capacities. Especially, strength andductility capacities were significantly improved when it is compared with the performance of building structures without the devices. Throughoutnonlinear dynamic analyses, it was observed that structural damages can be mitigated due to reduced seismic demands for seismic force-resisting systems. It is especially noted due to the fact that story drifts, accelerations, shear demands are reduced by 15~18%, 20~28% and 15~20%, respectively.
