COMPUTER APPLICATION OF CLM LATERAL LOAD ANALYSIS TO PILES AND DRILLED SHAFTS. TECHNICAL NOTE

The characteristic load method (CLM) for analysis at laterally loaded piles and drilled shafts can be employed to accurately estimate ground-line deflections and maximum bending moments for free-head and fixed-head piles in clay and sand. This technical note shares formulas for the nonlinear relationships used in the CLM for analysis of laterally loaded piles and drilled shafts. These equations can be used in spreadsheets or computer code to automate and simplify the analyses. The steps to be taken for spreadsheet analysis of loading conditions involving both load and moment are detailed.
