Abstract:	本研究針對消能接合板於斜撐構架耐震性能進行探討，利用建築物受地震力時之層間變位移，使斜撐產生軸向拉壓位移變化，消能接合板可讓斜撐受地震力變形集中，進而利用其應變能消散地震能量，其中消能變形集中於接合處，而非一般斜撐本身之主受力元件，斜撐本身能保持彈性不面外挫屈在外力加載時，消能接合板能提供一定強度的韌性進行消能，並在位移控制的初期進入塑性，此外消能器配置於半剛性抗彎構架，主要結構梁柱桿件不易降伏、破壞。為驗證此設計之可行性，研究中針對不同尺寸之消能接合板進行構件試驗，後經由適當配置不同尺寸之消能接合板應用於斜撐構架分別進行試驗以確認其應用性，研究結果顯示，此設計可以有效提升結構之承載性能，對於耐震性能提升具有相當可行性。 ;This study focuses on the seismic performance of the energy dissipating gusset plate in the brace frame. When the building is subjected to earthquake force cause the axial tension and compression displacement of the brace. The energy dissipating gusset plate can allow the deformation of the brace by the earthquake force. Then use its strain energy to dissipate the seismic energy. Among them, the energy dissipating deformation is concentrated at the gusset plate, rather than the main element of the structure itself. The brace can maintain elasticity without frustration. When external force is loaded, the energy dissipating gusset plate can provide a certain strength and toughness to dissipate energy, and enter plasticity at the initial stage of displacement control. In addition, the energy dissipater is arranged in a semi-rigid moment frame, and the main structural beams and columns are not easy to buckle or break. In order to verify the feasibility of this design, the research conducted component tests on energy dissipating gusset plates of different sizes, and then applied the energy dissipating gusset plates of different sizes to the brace frame to test their applicability. Experimental research results show that this design can effectively improve the load performance of the structure and is quite feasible for improving the moment frame performance.
