Preliminary pile tests are becoming increasingly routine in piling projects, some of which are
instrumented to help optimise working pile design. However, the execution of a successful …

To convert strain to internal force, it is conventionally assumed that both the foundation's
composite-section elastic modulus, E, and total cross-sectional area, A, are known …

Recent technological advancement of optical fibre sensing has led new ways in measuring
the performance of geotechnical structures. The distributed sensing, namely Brillouin Optical …

The incorporation of strain gauges (traditionally electrical resistance and vibrating wire
gauges but increasingly fibre optic sensors) within concrete piles enables an enhanced …

The distributed fibre optic sensor (DFOS) technology adopted in this study is based on
Brillouin scattering sensing technology known as Brillouin Optical Time Domain Analysis …

Continuous Flight Auger (CFA) and drilled displacement (DD) piles in the San Francisco
(California, USA) area are typically designed using a combination of side-and end …

A full-scale field demonstration project consisting of installation, instrumentation, testing, and
extraction of augered cast-in-place (ACIP) piles located in central Florida was undertaken in …

This paper presents a method to interpret the tensile test results for a concrete pile when the
concrete is stressed beyond its tensile limit, which results in anomalies in the strain gage …

A series of instrumented pile load tests was performed on augered cast in-place piles in an
area northeast of Austin, Texas. The site soils primarily comprised of clays. The load test …

Static pile loading tests and high strain dynamic tests were performed to confirm the
foundation design for a major expansion to a hospital on the Stanford University campus in …
