Abstract
A literature search was undertaken to assess the state-of-the-art in modeling the response of concrete structures to short-duration loading. The literature on concrete is vast, both on its constitutive modeling and the response of structures or structural components to various types of loading. Many structural geometries have been considered and a number of scholarly journals and a countable infinity of books, technical manuals and reports exist. Almost exclusively, these deal with the static behavior of concrete, that is, situations where the loading rate ranges from 0.0001/s to 0.01/s. Very little is available for dynamic loading, i.e., strain rates > 0.01/s. The main problem areas of interest are impulsive loading of structures and structural elements (e.g. blast, vibration and earthquake loads) and impact loading by kinetic energy and chemical energy projectiles (e.g. fragment and penetrator impacts resulting in penetration, perforation and extensive cracking, demolition of concrete structures by cutting charges, penetration of concrete runways and bunkers by bombs and the damage resulting from detonation of the explosive). These latter phenomena tend to occur at strain rates exceeding 100/s. TRUNCATED
