Abstract

This paper describes the performance of a fully instrumented test barrette subjected to an ultimate loading of 30932 kN. The load transfer characteristics were measured by vibrating wire strain gauges. Rod extensometers recorded the displacements at several locations along the barrette shaft. Test results indicated that substantial loads were carried in shaft resistance. The end bearing component was reduced by poor toe conditions caused by debris accumulation at the trench base. The load - displacement behaviour and factor of safety in barrette foundation design LS discussed. The toad test results of a subsequent working barrette confirmed that the performance of the barrettes designed as friction foundations in the Old Alluvium is satisfactory.

Barrettes Designed as Friction Foundations: A Case History

St. Louis, Missouri

This paper describes the performance of a fully instrumented test barrette subjected to an ultimate loading of 30932 kN. The load transfer characteristics were measured by vibrating wire strain gauges. Rod extensometers recorded the displacements at several locations along the barrette shaft. Test results indicated that substantial loads were carried in shaft resistance. The end bearing component was reduced by poor toe conditions caused by debris accumulation at the trench base. The load - displacement behaviour and factor of safety in barrette foundation design LS discussed. The toad test results of a subsequent working barrette confirmed that the performance of the barrettes designed as friction foundations in the Old Alluvium is satisfactory.
