近年來，歐美日等先進國家積極地進行應用纖維強化高分子複合材料（Fiber Reinforced Polymer,簡稱FRP）於鋼筋混凝土（RC）結構補強之各種相關研究，以解決RC結構物除了因設計、施工與使用不當及因材料老化與環境腐蝕所引發的維修問題。 目前國內外相關研究主要以試驗分析為主，對於FRP補強RC構件力學行為的理論探討與有限元素之數值分析模擬方面研究較少。因此本研究主要重點為研究FRP補強RC梁有限元素分析，應用非線性有限元素分析程式-ABAQUS，以ABAQUS混凝土及鋼筋材料模型與特殊內嵌於混凝土元素中之鋼筋模型，配合不同型態元素建立FRP補強RC梁之有限元素分析模型。以有限元素法分析、模擬與預測RC梁與FRP補強RC梁之力學行為，並探討RC梁有限元素分析時材料參數選用對於勁度與極限承載力之影響。 In recent years, modern countries in the world have paid more attentions to the maintenance problems of Reinforced Concrete (RC) structures caused by the inadequate design, construction, and operation as well as the aging of materials and corrosion in severe environments. In order to address these problems, there have been many research efforts made in applications of Fiber Reinforced Polymer (FRP) to the strengthening and retrofitting of RC structures. Most of research efforts in applications of FRP to retrofitting RC structures have been on experimental studies. There are only a few on theoretical studies, and very few on numerical simulations, such as finite element analysis. The goal of the present research is to analyze and predict the behavior and failure mechanism of RC beams and FRP-retrofitted RC beams using the nonlinear finite element package-ABAQUS. Also, the present research discusses the effect of material parameters used in the analysis on the predicted stiffness and ultimate load capacity of the FRP-retrofitted beams
