根據我國訂定相關的混凝土結構設計規範內容所興建之新造建築物多屬韌性配筋之耐震結構，相較於以往非耐震結構建物，具耐震設計之結構於設計地震力下之損傷應於可修復範圍內，然而如何修復或選擇適當之補修策略於國內鮮少被重視，因此本研究的主要目的是對其進行策略建議。
本研究共進行8組靜力循環加載試驗以及6組動力加載試驗(做為模擬地震歷時)，其中RC梁構件依混凝土設計規範採韌性配筋進行設計，試體之斷面尺寸設計為400 mm\times600 mm，淨長1800 mm試體之直立設計，混凝土設計強度分別為28 MPa與42 MPa。上述試驗規劃除了討論梁構件受反覆載重下裂縫發展及相關基本因子，另考慮試體經震損後(動力加載)在不同構件損傷程度下，採用不同方法修補對構件耐震性能之復原效果。本研究於不同損傷程度之構件分別採用表面處理工法、裂縫低壓灌注工法、環氧樹脂砂漿塗佈工法、植筋工法與鋼板補強工法進行試體復原，最後繼續採用靜力循環加載直至試體破壞，並將從試驗中所獲得構件的力量-位移曲線用於與原先施作之靜力試驗結果進行比較，其中包含裂縫寬度發展比較、構件剪力變形與撓曲變形之關係比較、強度折減因子、勁度折減因子、能量消散折減因子，並根據試驗結果針對梁構件復原後對耐震性能提升效益進行探討。

Based on the relevant concrete structural design codes established in our country, newly constructed buildings are mostly designed as seismic-resistant structures using ductile reinforcement. Compared to non-seismic structures in the past, structures designed for seismic resistance should sustain damage within repairable limits under design seismic forces. However, little attention has been given to how to repair or select appropriate repair strategies in the domestic context. Therefore, the main objective of this study is to provide strategic recommendations in this regard.
In this study, a total of 8 sets of static cyclic loading tests and 6 sets of dynamic loading tests (simulating seismic histories) were conducted. The RC beam specimens were designed using ductile reinforcement according to the concrete design codes, with a cross-sectional dimension of 400 mm × 600 mm and a clear span of 1800 mm. The concrete design strengths were set at 28 MPa and 42 MPa, respectively. The experimental plan encompassed discussions on crack development and related fundamental factors under repeated loading of beam specimens. Additionally, considering different degrees of damage to the specimens after seismic loading, different methods of repair were employed to assess the restoration effects on the seismic performance of the components. Surface treatment, low-pressure crack injection, epoxy mortar coating, rebar planting, and steel plate strengthening methods were applied to restore the specimens at different levels of damage. Subsequently, static cyclic loading was continued until specimen failure, and the force-displacement curves obtained from the tests were compared with the results of the initial static tests. This comparison included the evaluation of crack width development, the relationship between shear deformation and flexural deformation of the components, strength reduction factors, stiffness reduction factors, and energy dissipation reduction factors. Based on the test results, the improvement in seismic performance after the restoration of beam components was discussed.
