Development of Preliminary Load and Resistance Factor Design of Drilled Shafts in Iowa: Tech Transfer Summary
Despite possessing several advantages, drilled shafts are used infrequently in Iowa. The soil conditions in several regions of the state are ideal for using this foundation option. The reasons for the limited use of drilled shafts can be attributed to the following: • Lack of a formal process for selection of appropriate foundation types, especially in evaluating the advantages of drilled shafts over driven piles • Limited design guidelines and details for drilled shafts in the Iowa Bridge Design Manual • Absence of standard construction inspection checklists for drilled shafts Furthermore, the resistance factors for drilled shafts recommended in the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design Specifications (2010) were determined based on a general national database that does not reflect local design and construction practices and the regional soil conditions.
