本研究針對高強度鋼筋混凝土柱構件，建立一套於不同破壞模式下之遲滯行為模擬方法，其中包含材料參數之計算與流程，用以檢視既有或新建之高強度鋼筋混凝土建築受反覆載重作用時，側向強度衰減的過程，同時提供作為動力分析中，定義遲滯消能行為的基礎。
共蒐集了75座試體實驗數據做為模擬目標，為求提供模型之泛用性，試體材料強度及軸力為：混凝土抗壓強度介於67MPa至139MPa；縱向鋼筋降伏強度介於393MPa至744MPa；橫向鋼筋降伏強度介於341MPa至1424MPa；軸壓比介於0.07至0.62。並以ASCE/SEI 41-13提供之破壞模式準則為依據進行分類。撓曲強度使用輔助軟體NewRC-Mocur2020計算；剪力強度則參考高強度鋼筋混凝土結構設計手冊(第二版)，進行部分調整後計算得。最終判斷為撓曲破壞試體31座、撓剪破壞試體25座、剪力破壞試體19座。此結果與實驗結果高度吻合。
模擬遲滯行為使用開源軟體OpenSees建立模型，並以其資料庫中，Elwood開發之剪力極限狀態(Shear limit State)、LeBorgne開發之束縮極限狀態(Pinching Limit State)等概念，分別作為關鍵描述撓曲強度主控及剪力強度主控的側向力衰減過程。
分析成果顯示，既使在廣泛的材料性質下，於遲滯行為之擬合有不錯之成果。在整體強度的表現中，以模擬結果與實驗值比值作為指標，分別對三種破壞模式試體進行統計，其中撓曲破壞試體：平均值為0.93、變異係數為0.13；撓剪破壞試體：平均值為1.02、變異係數為0.07；剪力破壞試體：平均值為0.92、變異係數為0.11。顯示本模型具備一定程度之可靠性。

In this study, for reinforcement concrete columns using high strength materials, a hysteretic behavior simulation method under different failure modes was established, which could be used to examine the reversed loads of existing or new high-strength reinforced concrete buildings. Also, the process of lateral strength decay is provided as the basis for defining hysteretic energy dissipation behavior in dynamic analysis.
The experimental data of 75 specimens were collected as the simulation target. The material strengths of the specimens show as below. The compressive strength of concrete was between 67MPa and 139MPa. The yielding strength of longitudinal bars was between 393MPa and 744MPa. The yielding strength of transverse bars was between 341MPa and 1424MPa; The axial compression ratio is between 0.07 and 0.62.
Before starting hysteretic behavior simulation. The classification of failure modes should be conducted first. In this study, the method is based on the failure mode criteria provided by ASCE/SEI 41-13. Among it, the flexural strength is calculated using the program, NewRC-Mocur2020. The shear strength is calculated after partial adjustment with reference to the Design Manual for High-strength Reinforced Concrete Structures (Second Edition) provided by the National Earthquake Center (NCREE). In the end, there were classified in 31 flexural failure samples, 25 flexural shear failure samples, and 19 shear failure samples. This result is in good agreement with the experimental results.
To simulate hysteresis behavior, the open-source software OpenSees is used to build a model, and the concepts such as Shear limit State developed by Elwood and Pinching Limit State developed by LeBorgne are used as key descriptions in the model. These two defined the lateral strength decay process in failure behavior of flexure and shear, respectively.
