Evaluation of torsional load transfer for drilled shaft foundations: final report

Despite the prevalence of the use of drilled shafts for the support of traffic signal and signs along state highways, relatively little is known about the torsional load transfer between the structure and soil providing its support. To help address this gap in knowledge, two instrumented test shafts, which were designed to support signal pole type SM3 based on ODOT Standard Drawing TM653, were constructed to evaluate the torsional capacity of load transfer of these shafts at full-scale at the Oregon State University (OSU) Geotechnical Engineering Field Research Site (GEFRS).This archived document is maintained by the Oregon State Library as part of the Oregon Documents Depository Program.
