  • 目前在台灣一般仍使用極限應力設計法或工作應力法做構件設計,因此無法了解到構件在受力過程中損傷狀態,造成往後構件在受力後發生非預期損傷。因此,本研究以不同軸力比以及箍筋比之典型鋼筋混凝土柱構件為對象,首先介紹試體參數、配筋形式、加載方式,接著,將參考NCREE-13-023而得的力量與位移(變形角),與實驗值做比較,並驗證日本建築學會AIJ(2004)的裂縫寬度、卸載勁度與變形角之關係以及性能點,探討並建議最適合之性能點評估方法,接著,利用本研究建議之性能點評估式計算後,除建立柱構件之力量-位移曲線,也建立性能點、損傷階段、裂縫寬度與力量之關係,並提供給工程師在設計時使用,避免構件在受力後發生非預期損傷,最後,本研究將以實際建築物為例,評估其柱構件於地震受力後損傷狀態與力量之關係,由損傷狀態判定損傷階段後,可進一步推估殘留耐震容量,並判斷建築物損傷程度,作為工師於實務應用時之參考。


    So far Ultimate Stress Design method and Working Stress Design method are generally used to design members in Taiwan, therefore it’s not able to understand the damage state in the situation that members are subject to force, and it’ll cause unexpected damage after members are subject to force. Therefore, this study selects typical reinforced concrete columns with different axial force ratios and transverse reinforcement ratios as targets. First, introduce the parameters, arrangement of reinforcement, and the loading mode of the specimens. Second, compare the force and the deformation got referring to NCREE-13-023 with their experimental values, and verify characteristic points and the relation between deformation angle and crack width, residual stiffness from AIJ(2004), and then discuss the results and advise the most suitable evaluation methods of characteristic points. Third, after calculating characteristic points using the methods advised by this study, setting up the curve of force-deformation and the relation between characteristic points, damage level, crack width and force, and then offer them to engineers for design to avoid causing unexpected damage after members are subject to force. Last, this study will take an actual building for example to evaluate the relation between damage state and force after earthquake for its columns. After judging damage level by damage stage, it’s able to evaluate residual seismic performance and judge damage level of the building for engineer on the practical application.
