Modernize and Upgrade CANDE for Analysis and LRFD Design of Buried Structures (2008)

Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

23 Three companion documents are associated with this report: • CANDE-2007 User Manual and Guideline, • CANDE-2007 Solution Methods and Formulations, and • CANDE-2007 Tutorial of Applications. The full documents are included with the CANDE-2007 software and are accessible from the GUI toolbar. The abbre- viated table of contents of each document is shown on the fol- lowing pages at the chapter level. A P P E N D I X Table of Contents to Companion Documents
