Abstract:	耦合彎板阻尼器是適用於支撐框架中藉遲滯韌性彎曲產生消散地震能量的新設計。耦合彎曲板的反應取決於其非彈性階段之剛度和屈服強度。該耦合板的塑性彎曲取代了拉伸屈服和彈性挫屈。此有效增加能量消散。在大地震運動下，耦合彎板阻尼器具完整和穩定的遲滯行為，在拉伸和壓縮，提供顯著耗能和延展性。相對於其他替代的地震能量消散系統，此耦合彎板阻尼器具有容易更換及拉壓載重下穩定行為之特性。在這項研究中，進行了一系列關於耦合彎板阻尼器之循環荷載試驗和支撐框架之反覆載重試驗。試驗結果證實，此設計有效提升結構之強度、剛度、變形能力和能量消散，因此為一有效之耐震設計。;The coupled bending plate dampers is a new design of non-buckling braced system that applies on the braced frames to dissipate seismic energy through the hysteretic yielding within ductile bending plates. The hysteric response of a coupled bending plates depends on the inelastic behavior characterized by a post-yield increase in stiffness and strength at large displacements. The plastic bending of the coupled plates replaces the tensile yielding and inelastic buckling of traditional ductile braces. This gives a symmetrical hysteresis with increased energy dissipation. Under large seismic motions, the full and stable hysteretic behavior of the coupled bending plate dampers, which yields in both tension and compression, provides significant energy dissipation and ductility. Furthermore, when compared to other alternative seismic energy dissipation systems on the braced frames, the coupled bending plate dampers have advantages such as easy replacement following an earthquake and disallow damages in the main braced members. In this study, a series of cyclic loading tests on the coupled bending plate dampers and braced frames with the proposed dampers were conducted. The test specimens exhibited significant strength, stiffness, deformation capacity and energy dissipation which justified the effectiveness of the proposed design method. Keywords: Coupled bending plate dampers, energy dissipation, seismic performance, braced frame.
