MISSILE IMPACT ON REINFORCED-CONCRETE SLABS - EXPERIMENTAL AND THEORETICAL-ANALYSIS

This paper gives full analysis of the local failure of reinforced concrete slabs subjected to soft missile impact, where the missile is a deformable object, by using three-dimensional dynamic finite element analyses in which provision is made for the simulation of impact loads, plasticity and cracking of concrete. An assessment is made of perforation and scabbing. Three computer programs: NONSAP, MARC and OBAID have been used for comparison. The analytical results are well compared with those available from a model test. These results are very useful in the process of design of reinforced concrete slabs and give them integrity against hazards.
