Memorandum DS-3 presents guidance for analysis of drilled shafts under lateral loads for the following aspects:
I.Shaft Length
II.Minimum requirements for analytical models
III.Depth to fixity
IV.Considerations for collapse-susceptible soils
The intent of the memorandum is to present step-by-step guidance for latetal load analysis of drilled shafts. The guidance is also applicable for other deep foundations. Particular emphasis is placed on specific considerations for geotechnical stability, strength limit state and service limit state. Guidance is also provided for proper selection of analytical methods. Depth to fixity concept is discussed in detail. Finally, an approach for modeling collapse-susceptible soils while evaluating deep foundations in such soils is presented.
