Analysis of Live Loads on Culverts

By: Peterson D.L., Li G., Nelson C., McGrath, Timothy J.

Abstract: AASHTO Standard and LRFD Specifications differ in the manner that live loads are spread through fill onto culvert structures. Standard Specifications apply surface point loads, and spread loads at the rate of 1.75 times depths. The LRFD...
