Title: Implementation Report - Expanded Database for Service Limit State Calibration of Immediate Settlement of Bridge Foundations on Soil
Document Type: Report

Abstract
This implementation report presents an expanded database for calibration of the SE load factor for foundation movements in the AASHTO LRFD Bridge Design Specifications. The expanded database includes information from several state Departments of Transportation as well as other sources. Statistics are presented based on data from each source. Recommended values of SE load factors are developed. The effect of local geology and subsurface investigation techniques on the predicted values of SE load factors is discussed. This report will also serve as a useful reference for future researchers as well as agencies desiring to develop SE load factors based on local methods that are better suited to their regional geologies and subsurface investigation techniques
