Abstract:

The theoretical behavior of three buried structural configurations in a stress wave environment has been determined using finite element techniques. The three structures considered are an unlined cylindrical cavity and two thick-walled composite cylinders. Both composite structures are steel lined and each has a thick concrete outer layer one being cellular concrete and the other reinforced concrete. The impinging wave simulates an underground explosion and its strength was such that nonlinear behavior occurred in the soil-like surrounding medium NTS tuff as well as the composite structures.
