At the time of recording, no standard approach for the analysis of integral bridges appears in AASHTO LRFD Bridge Design Specifications or other international codes. This presentation considers the approaches most suitable for modeling common integral bridge forms, expanding upon recent guidance regarding soil-structure interaction approaches. Issues including material properties, initial stress state and the incorporation of the effects of soil ratcheting are discussed and both continuum and spring-type finite element models are explored. Paper presented at the 40th IABSE Symposium (Nantes 2018), Nantes, France, 19-21 September 2018 by Philip Icke and Steve Rhodes of LUSAS. A similar presentation for a paper presented at the European Bridge Conference in 2015 referencing metric units is also available.
