Numerical Investigation on Burial Corrugated Steel Culverts Design

Abstract

A full analysis and design theories have been reviewed conducted to determine response of a buried corrugated steel structural plate culvert for four exceptional shapes as; a round pipe, horizontal ellipse, arch and low profile arch. The select of culverts span, cover, and exceptional live load have been applied and all were have the same value. AASHTO LRFD Method has been used to measure the result of analysis and design by using manual and computer program techniques. Data collected by using computer controlled data acquisition system. The ultimate design strength of these type of culverts determined by manual analysis and CANDE finite element program. CANDE used to determine numerical results of factored thrust force and displacement of the shell at many point during the loading sequence. The CANDE numerical results compared with the manual analysis and design. Where the magnitude did not agree well between the manual results and the numerical simulations. The round pipe was the best choice from the other forms of the culvert shapes, due to it showed results in this study.
