Abstract:
The behavior and design of typical three-dimensional slabtoslab-to-slab joints for monolithic construction of blast containment structures and the reinforcement details associated with such facilities were investigated. Finite element simulations were done in the nonlinear dynamic domain with modified concrete and steel constitutive models. Deformations and stress distributions in both concrete and steel were examined to determine the composite structural behavior and damage after an accidental explosion. The simulations revealed structural behavior aspects and local stress distributions that could pose safety issues not addressed in current design approaches.
