||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.|
