Many important public buildings have suffered significant damages due to terrorist attacks in the last few decades. This paper investigates the behavior of structures with steel plate shear wall lateral load resisting system under various blast loadings. A number of twenty steel frames with different heights and widths subjected to four different blast scenarios are modeled and analyzed in opensees software. The results showed that structures with steel plate shear wall systems subjected to blast loading have better behavior in high-rise structures than in low-rise structures in terms of drift and ductility ratio. The steel plate shear wall system exhibited shear-dominated, flexural-dominated, and shear-flexural behavior in low-rise, high-rise, and mid-rise structures, respectively. Besides, in mid-rise and high-rise structures, the roof’s maximum horizontal acceleration occurs in free vibration, whereas in low-rise structures, this amount is experienced during loading. Furthermore, the maximum horizontal displacement of the roof occurs in free vibration, and as the number of stories increases, this amount will occur later.

在过去的几十年中，许多重要的公共建筑由于恐怖袭击而遭受了重大破坏。本文研究了在不同爆炸荷载下具有钢板剪力墙侧向抗力体系的结构的性能。在opensees软件中对二十种不同高度和宽度的钢框架进行了四种不同的爆炸场景建模和分析。结果表明，在爆炸荷载作用下，采用钢板剪力墙体系的结构在高层结构上的性能要优于在低层结构上的位移和延性比。钢板剪力墙体系在低层，高层和中层结构中分别表现出剪切为主，弯曲为主和剪切弯曲行为。此外，在中高层建筑中，屋顶的最大水平加速度发生在自由振动中，而在低层结构中，在加载过程中会经历此量。此外，屋顶的最大水平位移发生在自由振动中，并且随着层数的增加，此数量将在以后发生。
