中文摘要 本文主要以ABAQUS有限元素分析軟體,建立構架式鋼鈑補強立體構架模型,進行既有RC校舍構架式鋼鈑補強試體之單向側推分析,除了將其數值模擬結果與現地試驗進行比較,以驗證模擬方式之準確性與合理性。並進一步規劃補強鋼鈑厚度、樑柱接頭之樑端鋼鈑錨錠長度與既有混凝土強度等材料參數,探討不同參數變化對構架式鋼鈑補強效益之差異。研究結果顯示,本文之分析方法可以正確模擬校舍構架式鋼鈑補強試體之受力行為,並可應用於探討不同參數對於構架式鋼鈑補強效益之影響。比較結果發現補強鋼鈑厚度越厚,補強效果越好;樑端鋼鈑錨錠長度與校舍之耐震能力也有直接關係。本文所提出之有限元素模擬方式,可模擬結構體受力後之力學行為與構架式鋼鈑補強後之效果,能提供工程師初步評估之參考。
英文摘要 Using the finite element analysis program ABAQUS, this thesis investigates the behavior of school building retrofitted by steel-framing systems while subjected to monotonic pushover loadings. Both experimental measurements and numerical results are compared to verify the accuracy of the proposed finite element model. The results show that this analysis method can be used in the school building retrofitted by steel-framing system, and it can effectively simulate the loading behavior accurately. Furthermore, the proposed model is used to analyze three important design parameters of steel-framing systems such as the thickness of steel plate, original concrete strength, and various anchor lengths of steel plate. The findings from simulation results suggest that thicker plate and longer anchor length of the steel-framing systems can provide better seismic resistant capacity.
