Empirical analysis of strain rate effects on the behavior of concrete structures in the blast wave loadings and introduce a new mathematical model of concrete behavior

Behavior of concrete structures under quasi-static and dynamic loading conditions, are different. In this study the dynamic behavior of concrete at high rates Krnshhay, experimental basis using explosives of loading, and the results are compared with theoretical data. Explosive in the crimes and the different heights of the concrete form of the Persian month Tir Blvkhhay Sadhand are placed. Involvement with the static properties of concrete and pressure caused the explosion, increased load-bearing capacity obtained in dynamic mode comes. These tests measure the damage created cracks in the tensile region is considered tir. The results suggest increased dynamic factor (load-bearing capacity) rate of between 4.5 to 6 Bhaza’ Krnshhay 66s-1 80s-1 is up. These results with theoretical results and previous work conducted conforms. In the end, using Minitab statistical software using the method of experimental design (DOE), a quasi experimental mathematical model for concrete behavior under explosive load is introduced.
