dc.description.abstract自復位結構擁有承受地震後自行復位之能力,可降低結構受震後的殘餘變形。為達 結構物自復位之能力可採用預力系統,以施加預力的方式結合梁與柱構件,可達施工快 速、自行復位能力、經濟等優點。近年來國外學者投入相當多的心力在此研究上。採用 預力系統雖可使結構物在受震後自行復位,但因設計上儘量使梁與柱構件保持彈性,幾 乎無消能效果。然而若配合消能裝置,可以使結構物擁有額外的消能能力,降低地震力 對結構的損害。 本研究主要是針對鋼柱構件與基礎接合之自行復位能力與消能方式進行研究,將探 討預力的施加與消能裝置。利用預力鋼腱於柱構件與基礎接合施以預力,預力的大小將 影響柱構件自行復位的能力。消能裝置將採摩擦消能,探討摩擦消能裝置的設計與細 節,與其於結構行為的影響;摩擦消能裝置的設計可裝置於柱翼板或柱腹板處。研究方 法將先採理論推導,探討預力與消能裝置於柱構件與基礎接合之行為模式,進而規劃試 體進行實驗,以驗証其行為。以期建立柱構件自復位之行為模式,為工程實務之參考應 用。zh_TW
dc.description.abstractSelf-centering structures are designed with the capability of restoring to the original shape in order to reduce the residual deformation after subjected to earthquake. Post-tensioned beam and column members is an adequate way to achieve the self-centering of the structures, with the advantages of construction, self-centering and economic. Many research projects on the self-centering has been conducted. Although the post-tension can achieve the self-centering of the structures, there is merely no energy dissipation in the structures because the beam and column members are designed to remain elastic during the earthquake. To enhance the energy dissipation for the structures, an energy dissipative device can be supplemented to reduce the damage of the structures subjected to earthquake. This research aims to study the self-centering and energy dissipation for connection between column and foundation. Through the use of high-strength strands, post-tensioned the column and foundation. The magnitude of the post-tension will affect the behavior of self-centering of the column. Friction type energy dissipative devices will be designed and used to enhance the structural behavior. The friction type energy dissipative devices can be installed on the column flange or column web. Theoretic derivation will be conducted to investigate the behavior of the column base with post-tension and energy dissipative device. Specimens will be further designed and tested to validate the behavior. The behavior of the column base with post-tension and energy dissipative device can be further established to benefit the construction industry.en_US
