ANALYSIS OF SINGLE PILES UNDER LATERAL LOADING

The behavior of laterally loaded piles was investigated using the finite difference computer program COM623. A thorough search of the literature was undertaken to find the results of lateral load tests performed in clay and sand. The results of these analyses indicate that most of the p-y criteria, where p is the lateral resistance against the pile in force per unit of length and y is pile deflection, are satisfactory in predicting pile behavior. A modification of the p-y criteria of Reese and Welch (1975) was suggested, based on the results of some of the analyses presented in this report. (FHWA)
