Abstract:Currently (2007Currently ( -2010, AASHTO's LRFD design of deep foundations recommends resistance factors for a variety of scenarios (e.g., method of analysis, number of load tests, etc.). Generally, values account for a desired level of reliability and are based on comprehensive databases (not site specific) of predicted versus measured resistances. Unfortunately, no consideration is given to locations of boreholes with respect to foundation elements, to spatial variability of design properties over the site o… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
