RIGID PIPE PROOF TESTING UNDER EXCESS OVERFILLS WITH VARYING BACKFILL PARAMETERS: SECTION V, (VOLUME 11): NEUTRAL POINT ANALYSIS, P/S PIPE, (THEORY AND COMPUTER CODE)

Equations are developed to describe quantitatively the structural behavior of a prestressed concrete pipe with up to four wraps of prestressing steel and mortar brush coats. These equations are incorporated in a computer code used to analyze such pipes for a variety of loading conditions, either as specified by a designer or resulting from field experiments. In particular, the code will be used (in a subsequent volume, Section V, Volume 12) in the analysis of data for a prestressed concrete pipe at Cross Canyon. This volume includes development of the theory, a sample problem check, a flow diagram and listing for the computer code, the input format and sample input and output. (FHWA)
