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.Report number: cmr 14-011
