Concrete Structures under Impact Loading Rate Effects

摘要

There is a need for reliable assessment methods for the local and the overall response of concrete structures to impact. The numerical methods - in particular the finite element method - enable extensive parameter studies to be carried out and should be treated as complementary to experimental methods. A dynamic analysis of simple mechanical models with non-linear elastic material characteristics may provide a rough approximation of the global response of the structure to impact. For a more accurate dynamic analysis, advanced finite element codes should be used together with realistic models for reinforced concrete. The material models should account for the rate sensitiveness of materials discussed in the report.
