| Sumario: | One of the aims of passive defense, is designing of safe structures against explosion. Nowadays, with expansion of bombing attacks into the building, it is necessary to investigate the behavior of structures under blast loads. In recent years, Steel plate shear walls (SPSWs) have become an increasingly popular lateral force resisting system in building. Low cost, quick installation and high energy absorption potential, has made SPSWs as a suitable system for strengthening existing structures. Considering the prominent features of easy going steel plate wall against lateral loads, such as high energy absorption, good ductility and hardness increasing and displacement reduction, study the behavior of this system against blast loads is necessary. Therefore, in this paper by modeling of SPSW specimen in the finite element software ABAQUS , verification of modeling and software work, were examined as compared to the experimental data. Then structural steel plate shear wall and Easy going steel plate shear wall by AISC 20 Design Guide were designed, and both systems, with thicknesses of 1, 1.5, 2 and 2.5 times the designed plate thickness were investigated under the near and far field explosions. Results of these analyses showed using Easy going steel plate in shear wall systems caused reduction of steel frame displacement. Also by Increasing the plate thickness of both Easy going steel and structural steel systems, under the near and far field explosions, displacement decreased. |
