LRFD Example Problem 2 – CIP Wall with Sloping Backfill
This example problem presents a detailed solution for a typical cast-in-place (CIP) wall used by the Arizona Department of Transportation (ADOT). A sloping backfill configuration is assumed. The solution uses ADOT policies to demonstrate the application of LRFD principles in analyzing the external stability limit states that include...

Document Info Title: Selection of Spread Footings on Soils to Support Highway Bridge Structures Authors: Naresh C. Samtani, PE, PhD, Edward A. Nowatzki, PE, PhD, Dennis R. Mertz, PE, PhD Report Date: February 2010 Sponsoring Agency: Federal Highway Administration (FHWA) Abstract The FHWA believes that spread footings on soils are underutilized because designers encounter one or more of the following obstacles: (a) limited knowledge of AASHTO/FHWA technical references that pertain to spread footings...
