Description: Technical Report
Abstract: Five box structures with span-to-depth (L/d) ratios of 10, 1 percent reinforcement in each face, and concrete strengths of approximately 4000 and 6000 psi, and six box structures with L/d ratios of 7, concrete strength of approximately 7000 psi and steel percentages of 1.2 and 0.75 percent, were tested dynamically at depth of burial equal to L/5. The dynamic overpressure simulated the peak overpressure, rate of pressure decay, and load duration associated with nuclear detonation and was generated using high-explosive primacord in a Foam HEST charge cavity configuration placed over the structure at the ground surface. Results of these tests indicate that current dynamic shear failure criteria significantly underpredict the dynamic shear strength of these structures. NOTE: This File is large.
