Abstract : The objective of this project was to investigate the predicted behavior of French underground personnel shelters, equipment, and instrumentation. Data were used for the evaluation and improvement of present designs and for the establishment of design criteria. Five reinforced-concrete underground structures designed by French engineers were tested: one cast-in- place rectangular structure, one precase circular shelter, two entranceways at approximately the 116-psi peak overpressure range, and one entranceway at approximately the 105-psi range. Reinforcing steel, doors, ventilation equipment, precast rings for the circular structure, and instrumentation were shipped from France and incorporated in the shelters. Preshot and postshot preciselocation surveys were made to determine the total lateral and vertical motions of the structures as a result of the blast. Shock spectral data indicated substantial transient vertical and horizontal motions. Most test structures sustained very slight damage in the shelter areas.
