Protective Structures

Extensive use of reinforced concrete to build shock-protective structures calls for adequate analytical expertise to facilitate rational and safe structural designs. Although several researchers have studied these problems, there are still some uncertainties, particularly with regard to strain-rate effects. This paper presents a simplified, but accurate, numerical procedure for modeling the nonlinear behavior of reinforced concrete, using solid finite elements, which include strain-rate effects. The details of the material modeling for anisotropic concrete and isotropic steel are presented. A clamped circular plate subjected to uniformly distributed load and a clamped rectangular slab subjected to jet force are analyzed using 8-noded solid finite elements. Strain-rate effects are considered in the analyses.
