Book Description
The objective was to provide instrumentation, electronic and self-recording, for obtaining air-blast and ground-shock loading and response of the structures employed by the various structures projects. Included was installation of transducers, recording of transducer signals, and presentation of the recordings as nonlinearized time-dependent plots of the measured variable in the specified appropriate units. A total of 430 recording channels was utilized; of these 161 were electronic recording on magnetic tape, 225 were used for self recording time-dependent guages, and 44 were peak-indicating. A basic description of the instrumentation employed by the Ballistic Research Laboratories in taking the structural measurements is given in this report.

Book Description
Power-transferring equipment was designed to change from a-c to d-c power prior to shot time. The d-c power was supplied by storage batteries to motors driving 110-volt 60-cycle single-phase alternators which operated all the instrumentation.

Book Description
Project 30.2 was conducted to test a reinforced-concrete dual-purpose underground parking garage and personnel shelter designed for a long-duration incident pressure of 40 psi. The shelter was exposed to shot Priscilla, an approximately 37-kt 700-ft balloon burst (June 24, 1957), at a ground range of 1600 ft (predicted 35-psi peak incident-pressure level). The recorded peak incident pressure at the shelter was approximately 39 psi. Postshot soil boring were made to obtain undisturbed samples for determining soil characteristics. Preshot and postshot field surveys were made to determine the total lateral and vertical displacement of the structure. Blast instrumentation consited of Wiancko pressure gauges, Carlson earth-pressure gauges, dynamic-pressure gauges, and a self-recording pressure gauge. Structural response was recorded by Ballistic Research Laboratories deflection gauges. Radiation measurements were taken using film dosimeters, gamma-radiation chemical dosimeters, and one gamma-rate telemetering unit. (Author).

Book Description
The effectiveness of frangible backfill (glass bottles) in protecting underground structures from the violent motions produced by nearby explosions was investigated. Two test structures and one comparison structure were used. Each test structure was a reinforced concrete pipe enclosing a steel cylinder separated from the pipe by rubber O-rings, with glass bottles placed around the sides and bottom of the pipe. The comparison structure was a concrete pipe with solid concrete bottom. All three structures were buried with their axes vertical, and their tops approximately 2 feet below ground level. A concrete slab 1 ft thick was set above each, flush with the ground surface. One test structure and the comparison structure were 750 feet from ground zero (229-psi peak verpressure). The remaining test structure was 1,050 feet from ground zero (104-psi peak overpressure). The peak accelerations of these structures, produced by shear forces exerted against their sides, were reduced by the frangible backfill to 26% or less of those that structures in intimate contact with the soil would have experienced. Four years after the shot the structures were excavated. All the bottles around the sides of the test structure at 229 psi were completely crushed; only a fourth of the bottles at the 104 psi were broken, most of these on the upper half of the structure.
