使用FRP補強結構物是施工的趨勢，因此有必要提出一套合理及高可信度的有效分析方法，提供工程實務界的評估使用。此分析方法，必須考慮到材料非線性行為，並利用現有的實驗研究成果來驗證分析模式。

本文結構物是採用FRP補強預力鋼筋混凝土，對不同材料的模型，提出合理的非線性分析模式，利用有限元素軟體ABAQUS來分析，並與實體試驗資料驗證，所得之分析結果，可供日後之數值分析參考。參數部分的分析，主要以預力混凝土板為主，討論空心板與實心板補強後，板之極限強度的變化。

The current trend in construction is to use FRP as reinforcement in concrete structures. Therefore, a reliable and effective analysis method is needed to offer for practical engineering applications. This method must take into account nonlinear behavior of materials and consist with the existing experimental research results.

This paper shows a reasonable nonlinear model of different material to simulate of FRP reinforcement in the prestressed concrete structure with the commercial FEM software, ABAQUS, and compare with the experimental data for verification. It can be served as a reference for future numerical analyses. The prestressed concrete slabs are focused in the parametric analysis. It discusses the change of ultimate strength after FRP reinforcement in the reinforced solid and voided slabs.
