    Abstract: 近斷層地震在近年來在土木工程領域中備受關注,其原因為在同一次的地震中,近斷層區域得到的紀錄與遠場區域得到的紀錄相比,有許多顯著的不同特徵,例如:速度脈衝、滑衝效應、破裂方向性等特徵,危害性也比較大,因此建築物在近斷層地震力的作用下,有可能遭受非預期的嚴重破壞。本研究建立三種不同樓層的抗震耦合結構牆之分析模型,分別為十、十八與三十層樓模型,其中,耦合結構牆是由兩個以上之結構牆(structural wall)藉由連接梁(coupling beam)所連結而成一整體之結構物,在地震頻繁的區域,耦合牆常用以增加系統的側向勁度,另外加入鎳鈦形狀記憶合金(Ni-Ti Shape Memory Alloy,簡稱SMA)於連接梁、結構牆等區域,探討耦合結構牆加入SMA於近斷層地震(Near-fault earthquake)作用下之結構動態行為,分別進行非線性側推分析、反覆加載分析、與不同層級地震下的非線性動力分析,文中並以系統層間變位、結構牆與連接梁轉角等結構參數,評估耦合結構系統之損害。結果顯示,SMA加入耦合牆之連接梁中,能發揮其超彈性性能,降低結構體於加載後之殘留變形。;In recent years,near-fault earthquake much pay close attention in the field of civil engineering. The reason is in the same earthquake, compared near-fault region records with far-field region near fault region , there are many different characteristics. For example, velocity pulses, fling-step effect, and rupture directivity effect etc. Harmfulness is relatively large. Therefore, the building under the action of near-fault earthquake, there are likely to suffer serious damage unexpected. In this study, the seismic analysis model coupled structural walls of three different floors, respectively, ten, eighteen and thirty level floor model,wherein the coupling structure is composed of two or more of the wall structure wall by connecting beam linked together a structure. In earthquake-prone region, coupled wall commonly used to increase the lateral stiffness of the system. Followed by addition of Ni-Ti shape memory alloy in connection beams, structural walls and other areas, discussion coupled structural walls joined SMA in the dynamic behavior of structures under near-fault earthquake effects were nonlinear pushover analysis, repeated load analysis, and nonlinear dynamic analysis under different levels of seismic. In the study, inter-system layer structure parameters of displacement, structural walls and connecting beam angle, etc., to assess the damage of the coupling structure of the system. The results show, SMA added to the coupling of the connection wall beams, can play its super-elastic properties, to reduce residual deformation after loading the structure.
