LOAD FACTOR DESIGN FOR SUBSTRUCTURES AND RETAINING WALLS

An evolution of design specifications from working stress to load factor design has occurred over the last 20 years. This project continues that activity with application to substructures and retaining walls. Load factors and capacity modification factors are derived for checking limit states for retaining walls, footings and piles. These factors have been calibrated to current design results to avoid significant changes in section sizes. A survey of design practice is discussed with questionnaire responses from over 30 states. Soil strength factors are proposed for friction and cohesion and a range of strength factors considered for piles evaluated by static methods, dynamic formula, wave equation and load tests. Recommendations for code revisions are presented.
