Abstract:

A research project involving 32 drilled shaft load tests was undertaken to establish LRFD procedures for ; design of drilled shafts subjected to lateral loads. Tests were performed at two Missouri Department of ; Transportation (MoDOT) geotechnical research sites. All shafts were founded in shale. Shafts were ; instrumented to measure the displacement of the shaft head, and the structural response of each shaft was ; interpreted from strain gage data as well as from ShapeAccelArray (SAA) data. The load tests achieved ; significant displacement of the top of the shaft, and successfully transferred load into the rock layers. A p-y ; model was created from the data by using a FEM code to match the measured deflection data. The fitted p-y ; models were generally stiffer and with greater values of than those predicted using the popular “stiff ; clay” model of Ensoft’s L-PILE. The FEM code was then used to perform reliability calculations and ; produce resistance factors as a function of the coefficient of variation of the foundation material strength
