Two recent trends have significant consequences for the design of drilled shaft concrete. First, longer service lives make drilled shaft durability imperative. Second, larger drilled shafts increase the challenges of providing workable, stable concrete mixes that avoid damage due to thermal distress. TRB hosted a webinar on Tuesday, May 25, 2021 from 2:00-3:30 PM Eastern that explored challenges associated with concrete for drilled shafts, especially large-diameter drilled shafts. Presenters discussed requirements for workability, stability, and long-term durability, including with respect to thermal issues. They also illustrated a design methodology for predicting drilled shaft concrete temperatures to establish performance criteria.
This webinar was organized by the TRB Standing Technical Committee on Foundations of Bridges and Other Structures.
The slides and recording are available.
