本研究以橋梁側推模式分析模式，以鋼筋腐蝕程度與服務時間及環境之關係。考慮鋼筋腐蝕對保護層、鋼筋材料性質及對鋼筋握裏性質之影響，進行選現有之橋梁之腐蝕評估。將鋼筋及混凝土之材料參數加以修正，得到修正後的材料參數。
再將修正後之參數輸入軟體中（Xtract）做分析（第一次以靜力析所求得為輸入之柱軸力），計算鋼筋腐蝕後斷面構件之強度。由Xtract軟體分析計算出之構件斷面強度來分析，並作斷面強度判定，求得塑性鉸資料代入SAP2000進行側推分析，本研究選擇現有之橋梁（橋長2,611m）橋梁，本橋梁於民國80年代建造採用替代工法允許廠商於投標時提出替代工法為一特色，進行考慮腐蝕情況之側推分析。並將求取之Ay、Ac值與考慮腐蝕情況橋梁之Ay、Ac值比較，以驗證橋梁受腐蝕的影響。

In this study, the bridge mode pushover analysis model to the degree of reinforcement corrosion in service hours and environment relationship. Consider about corrosion on the protective layer, reinforced steel grip on the material properties and the impact in nature, select a Highway Bridge corrosion assessment. To correct the steel and concrete material parameters, and obtain material parameters.
Then,input correction parameter for analysis by the software (Xtract) ,(static analysis of the first to obtain the input of the column axial force), calculate the cross member reinforced the strength of corrosion. Xtract calculated by the software analysis to analyze the components section strength and determination of cross-sectional strength, and seek information into SAP2000 plastic hinges for pushover analysis. Meanwhile, the Highway Bridge (bridge length 2,611 m) constructed in the Republic of 80s alternative construction method allows vendors to propose an alternative bid is a specialty engineering methods for considering corrosion of pushover analysis. And the values of Ay,Ac we obtain considering corrosion bridges Ay, Ac value comparison, to verify the impact of the bridge corroded.
