A Ground-Motion Displacement Gauge.

Abstract

This report describes a ground-motion displacement gauge and its applications. The gauge concept is based upon the free-fall time of a mass released inside a gauge cannister prior to the onset of ground motion. The time-of-fall of the mass to the cannister bottom during ground displacement, together with the free-fall time for the gauge at rest, uniquely determines the vertical displacement at one time. Simulation of ground displacement by gauge drop tests demonstrated the operating principle. (Author)
