  4. Abstract:
  5. 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. © 2021, Korean Society of Steel Construction
