The behavior of a laterally loaded drilled shaft in clay was investigated by conducting a lateral load test on an instrumented shaft. Lateral deflections, shaft rotation, and soil resistance were measured for each applied load. Dial gages were used to measure lateral deflection, and the shaft rotation was determined by means of an inclinometer. Pneumatic pressure cells were installed in the shaft at various depths to measure the soil resistance. The applied lateral load was measured by using a strain-gage load cell. Structural failure of the shaft occurred before the soil failed and prevented determination of the ultimate lateral soil resistance. However, the ultimate soil reactions predicted by several analytical procedures were compared with the soil reaction calculated from the maximum recorded soil resistance. Also, as ultimate lateral load for the test shaft was predicted by various analytical methods, and a comparison was made between the maximum recorded load and the various predicted ultimate loads. Finally, a comparison was made between two ultimate test loads reported in the technical literature and the ultimate loads predicted by the analytical methods. (Authors)
