Recommended Design Specifications for Live Load Distribution to Buried Structures

Download or read book Recommended Design Specifications for Live Load Distribution to Buried Structures written by D. Lee Petersen and published by Transportation Research Board. This book was released on 2010 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides recommendations to revise the AASHTO LRFD Bridge Design Specifications relating to the distribution of live load to buried structures. The report details the development of simplified design equations (SDEs) for structural response based on three-dimensional (3D) analysis of 830 buried culverts. In addition, the report provides guidelines for conducting 2D and 3D modeling for design situations with conditions not covered by the SDEs. The material in this report will be of immediate interest to roadway and bridge designers.
