摘要
本研究以不同非線性分析方法模擬鋼筋混凝土構架，並整理出側推分析方法之流程與應用，一是考慮鋼筋混凝土材料非線性，將斷面切割成數元素以進行分析，二是計算鋼筋混凝土斷面彎矩與曲率非線性關係，並利用彎矩與曲率來進行構架分析，最後則是先將鋼筋混凝土柱進行非線性側推分析，利用容量曲線圖定義以模擬集中彈簧彎矩與轉角行為分析方式模擬。 本研究以所建立非線性分析程式與國家地震工程研究中心所模擬塑性鉸模式進行門型構架之非線性側推分析，並討論之間差異。最後則進行較大構架實例分析，以非線性材料之側推分析導出集中彈簧係數進行分析，將分析結果之容量曲線圖與彎矩位移關係圖進行比對判斷塑性鉸發生位置與順序。

This research simulates the reinforced concrete frame in different nonlinear analysis method, and reorganizes the flow and the application pushover analysis method; first, to consider the reinforced concrete material nonlinear, cuts the round number element by to analyze the cross section; second, to calculate the reinforced concrete cross section bending moment and curvature nonlinear relationship, and carries on the frame analysis using the bending moment and curvature, finally first carries on the nonlinear pushover analysis the reinforced concrete column, to simulate the centralized spring bending moment and corner behavioral analysis way simulation using the capacity diagram of curves definition. This research by establishes the nonlinear analysis program and national center for research on earthquake engineering the simulation plastic hinge pattern carries on the portal frame the nonlinear pushover analysis, and discussed the difference. Finally carries on big frame case study, derives the centralized spring constant to analyze by pushover of analysis the nonlinear material, capacity of diagram of curves and bending moment displacement relational graph the results analysis will carry on the contrast judgment plastic hinge to have the position and order.
