　　有鑑於近年來921集集地震和2016年美濃地震造成的地震危害，台灣的鋼筋混凝土結構易受到偏心和扭轉不規則的破壞。因此，專家和學者們致力於扭轉不規則結構的抗倒塌分析和模擬，並使用大型振動台試驗針對一系列具有不同扭轉不規則來源的半尺度七層樓鋼筋混凝土結構進行測試，期望可以對鋼筋混凝土結構的非線性扭轉反應進行研究。
　　本研究旨在透過NCREE所進行的振動台試驗，研究既有鋼筋混凝土建築物在近斷層地震作用下的非線性扭轉行為，並強調軟弱底層系統的特性。搭配使用有限元素分析軟體“ ABAQUS”進行動力分析，並詳細討論如何建立合適的分析模型來有效地模擬其結構勁度、混凝土的塑性行為、破壞模式和非線性扭轉反應。最終，將通過模擬分析獲得的動態行為和相關數據與NCREE量測到的實驗數據進行比較，討論非線性扭轉分析技術的準確性，並提出結論和未來的建議。

In view of the recent earthquake damage caused by the 921 Chi-Chi Earthquake and the 2016 Meinong Earthquake, reinforced concrete structures in Taiwan are vulnerable to eccentric and irregular torsional damage. Therefore, experts and scholars are devoted to the analysis and simulation of the collapse resistance of the structures with torsional irregularity, and a series of half-scale seven-story reinforced concrete structures with different sources of irregularities were tested on the shake-table at the National Earthquake Engineering Research Center (NCREE) Tainan laboratory. It is expected that the nonlinear torsional response of the reinforced concrete structures can be experimentally studied.
This study aims to research the nonlinear torsional behavior of existing reinforced concrete buildings under seismic motion through the shake-table tests performed by NCREE, and emphasize the characteristics of the weak first-story system, and use the finite element software “ABAQUS” for dynamic analysis, which discusses in detail how to establish an appropriate analysis model to effectively simulate its stiffness, plastic behavior of concrete, failure mode and nonlinear torsional response. Finally, the dynamic behavior and related data obtained by simulation are compared with the experimental data measured by NCREE to discuss the accuracy of the analysis technology for nonlinear torsion, and draw conclusions and future suggestions.
