NUMERICAL-STUDIES OF IMPACT ON REINFORCED-CONCRETE BEAM OF HARD MISSILE

The safety design of concrete containment structures in nuclear power stations has thus far covered only accidents due to internal pressure, temperature loading and earthquake loading. Recently, designers and r esearchers have become interested in the important effects of the impa ct load of a projectile on nuclear power stations. This paper develops an FEM model for analyzing the collision of a hard missile against re inforced concrete structures and compares the results with impact test s conducted at our institute.
