ABSTRACT Instruments are described which were used to measure the blast effects on the structures during Operation Greenhouse. Measurements made on buildings included air pressure, acceleration, displacement, strain, earth pressure, footing pressure and time-of-break measurements. In addition Stimascope (sound-time-in materials) tests, Whittemore strain gage tests, surveying measurements, and natural periods of vibration measurements, were made before, and repeated after, the blast. The magnitude of the task limited the type of end measurements to the simplest that would give adequate information. Availability, cost, and ease with which gage responses could be remotely recorded on magnetic tape, were also controlling factors in the selection of the instruments used. A list of the equipment, photographs, diagramatic drawings and wiring circuits, and data from preliminary tests of the equipment are included. 801.
