Experimental and Numerical Analysis of Scale Model Protective Door under Blast Loadings
Recent terrorist events have led to changes in the policy of protecting important buildings. In addition to protection
of structural elements, more attention is now given to access elements to the building (doors with various shapes and
configurations), some of them requiring greater protection against extreme actions such as blast loadings. This paper presents
experimental and numerical results on establishing a proper configuration to ensure a minimum level of blast protection. The
experimental tests and numerical analysis were performed on a 1/3 scale model. Steel plates with and without polyurea
coating were tested in order to determine the real behavior of metal doors under explosion. The numerical results showed a
good correlation with numerical ones, permitting the further development of a full-scale model.
