碩士 === 國立中央大學 === 土木工程學系 === 102 === This study focuses on the evaluation of seismic performance of Y-shaped knee braced moment resisting frames (KBRF) with friction dissipation devices. The performance of friction energy dissipation device has been proven in many research studies. Brass plates were used as friction devices in this study. This system dissipated energy through friction rather than the inelastic yielding during the earthquake excitation. It was found from the tests that significant energy dissipation was achieved before structural members reached inelastic stages. The failure locations of the KBRFs could be controlled by adequate selection of the eccentric ratios of the knee braces. The beam end moment of the KBRF was significantly reduced compared with the moment resisting frame (MRF) with similar dimensions. Test results also showed that the strength and stiffness of the KBRFs were significantly enhanced when Y-shaped knee braces were adopted which justified the applicability of the structural systems.
