Abstract
In this study the interaction effects of dual pipe systems are investigated. The study focuses on concrete pipe buried under large fill heights. An investigation is made of various methods of analysis. The main purpose of this report, however, is to study the behavior of two pipe systems. A mathematical model using the finite element analysis method is used to represent the dual pipe system. Utilizing this model, the loads applied to the outside face of the pipe are calculated. The magnitude and distribution of applied loads on the pipe are plotted and compared to determine the effect of dual pipe interaction. The finite element loadings are then compared with the loadings of the Marston-Spangler analysis method. A plane frame model of the pipe is developed, in order that the internal response of the pipe due to applied loads can be calculated. The finite element, Marston-Spangler, and three edge bearing test loadings are applied to the pipe. The resulting internal forces are then determined. Once the internal forces are known, the required areas of reinforcing steel required to resist bending moment are determined. The effect of dual pipe interaction and the effect of the method of analysis on internal forces and steel areas are investigated. Finally, the conclusions of this study and recommendations for future research of dual pipe systems are offered.
