Evaluation of Blast Resistant Rigid Walled Expeditionary Structures (PREPRINT)
Abstract
Blast and fragmentation resistance of expeditionary shelters has become of great interest given the current threat environment. One such structure now being considered for deployment utilizes an ISO container sized steel frame with infill panels. The panels consist of a lightweight extruded polystyrene core sandwiched between two galvanized, light-gauge steel sheets. An investigation was conducted into the blast and fragmentation resistance of this new type of shelter and a direct comparison was made to that of a typical ISO container shelter currently deployed in theater. The static resistance function of the panel system was determined in the laboratory via two experimental methods. A 16-point loading tree simulating a uniform load was utilized on a variety of full-scale panel cross-sections representing seven panel configurations. A vacuum chamber was employed to accomplish static full-scale wall testing. Laboratory resistance data was used to model the dynamic response of the panel system using a single-degree of freedom (SDOF) analysis. Accuracy of the analytical model was verified via three arena blast experiments, each of which included an instrumented ISO container for direct data comparison.
