ارائه یک مکانیزم مناسب جهت کاهش فراجهش سازه تحت بار انفجار

as in order to protection of a blast loaded structure, three ways can be utilized: (1) increasing the stand-off using natural or artificial barriers, (2) increasing the structure strength or performance level, (3) decreasing the energy of blast using the passive, semi active, active and hybrid control methods. In recent method, using controlling mechanism and tools, the effect of blast waves is decreased and the structure response is controlled. In this research, considering the third way, a system including mass, spring, friction damper and viscous damper is presented and its performance on reducing the response against blast is evaluated utilizing numerical analysis. Generally, inability of system in endurance of maximum responses leads to damage and collapse of structure undergone blast load. Thus, finding an effective mechanism to achieve an acceptable structure performance and decrease of system overshoot, can help to design of the structure endures the blast.
