Abstract

PIPE5 is a finite element analysis (FEA) program designed to analyze buried pipes and culverts whose development was spearheaded by A. P. Moser. PIPE5 started as a modification of the program SSTIPN in 1981 so that the program could run in batch mode on a mainframe and was written in Fortran IV language. Various students made modifications to the original code making it compatible with personal computers and adding additional features. For more history on early PIPE5 developments see Moser [1]. In 2003 Mr. Merrill began a project of updating PIPE5. Mariner did extensive work on making the code compatible with the Fortran 90 standard and adding a graphical user interface. While Mariner made significant modifications to PIPE5 there are still elements of the program that could be updated.

PIPE5 has been improved many times since its creation. For the sake of clarity the program before Mariner’s modifications will be referred to as PIPE5v1. The program as Mariner left it will be called PIPE5v2. The program in its current form with the improvements detailed in this thesis will be known as PIPE5v3.

This thesis will document the changes to PIPE5v2 that produced PIPE5v3. The following list of objectives covers most of the changes made to PIPE5v2.
