Abstract

The purpose of this study was to develop a method to predict the behavior of unreinforced concrete construction joints using the computer program GT STRUDL. Two three-dimensional finite element models of a navigation lock wall were constructed. The wall was subjected to eccentric prestress forces, which brought about concern for lift-off within the lock wall.

Eleven loading combinations were evaluated, which were created from seven independent loading conditions. Stresses for each loading combination were compared to nominal strength values as detennined by ACI 318-02, Chapter 22, for plain concrete. Results show the stresses to be acceptable throughout the wall and displacements to be negligible; thus, the structural integrity of the lock wall is adequate for continued operation.

A detailed description of the study including the computer modeling, results, and recommendations are discussed in this thesis.
