..., leading to sudden release of confining stress. To confirm this hypothesis, affected areas of the curtain wall were instrumented with accelerometers and deflection gages strategically located to pinpoint the origin of the noises. To further confirm the point-of-origin identified by the accelerometers...

... For laboratory weathering instruments to be most useful, they must have, among other qualities, the ability to conduct tests repeatably and reproducibility. Repeatability is the measure of a specific instrument's ability to duplicate results from one test to another. Reproducibility...

... for a capillary break in order to reduce frost action. An integral drainage collection system was installed to collect the water flowing in the geonet. This paper includes a project description, material and construction specifications, installation procedures, instrumentation, and test results based upon two...

... are based on input soil properties such as subgrade modulus, friction angle, undrained shear strength, etc. Soil properties must be deduced by laboratory testing or correlation to in situ test results. This is a source of uncertainty. In a few cases, lateral load tests are performed on instrumented piles...

... An extensive instrumentation plan was devised to monitor large-span culvert behavior, soil behavior and culvert-soil interaction during backfilling and during live load testing. The goals of the instrumentation plan were to help control construction deformations, including insuring safe working...

... An extensive instrumentation plan was devised to monitor buried pipe behavior, soil behavior and pipe-soil interaction during backfilling. The emphasis of the instrumentation plan was to monitor these parameters under different installation techniques without impeding construction operations...

... The purpose of this paper is to present the effectiveness of in-situ instrumentation on diagnosing the pavement layer conditions under full-scale accelerated traffic loading. The test section is an in-service pavement (US281) in Jacksboro, Texas. Multi-Depth Deflectometers (MDDs) are used...

... for the 140 ha (350-acre) municipal solid waste landfill. The soils beneath the landfill have been extensively instrumented to measure pore pressure, settlement and deflections, using inclinometer casings, standpipe piezometers, vibrating wire piezometers, pneumatic piezometers, settlement plates, liquid...

... most historic and prestigious buildings, consequently stringent limits were imposed upon ground and structure movements. To control these movements and remain within the limits set, a comprehensive monitoring system was required, comprising a wide variety of instruments linked to a geotechnical...
