Title: Serviceability limit state reliability-based design
Abstract: In foundation design, the serviceability limit state often is the governing
criterion, particularly for large-diameter piles and shallow foundations.
In addition, it is widely accepted that foundation movements are difficult
to predict accurately. Most analytical attempts have met with only limited
success, because they did not incorporate all of the important factors, such
as the in-situ stress state, soil behavior, soil-foundation interface characteristics, and construction effects (Kulhawy, 1994). A survey of some of
these analytical models showed that the uncertainties involved in applying
each model and evaluating the input parameters were substantial (Callanan
and Kulhawy, 1985). Ideally, the ultimate limit state (ULS) and the serviceability limit state (SLS) should be checked using the same reliability-based
design (RBD) principle. The magnitude of uncertainties and the target reliability level for SLS are different from those of ULS, but these differences
will be addressed, consistently and rigorously, using reliability-calibrated
deformation factors (analog of resistance factors).
