Abstract
The structural behavior of an airfield pavement system under multiple heavy wheel loads is a big concern with the new generation of aircraft. Interactions between wheels are expected to be important because of the relatively small wheel spacing (145 cm for a B-777) and high tire pressures (1.5 MPa). Three-dimensional finite element analysis can help to understand the complex behavior of a pavement under multiple wheel loads. This paper is a case study in which we examine various loading patterns and positions with different material properties and interface conditions. The section studied is modeled after a section of the Denver International Airport. Comparisons of maximum bending stresses and displacements from different landing gear configurations (single, tandem, dual-tandem, and tri-tandem) are made. An edge loading case was found to be the most critical case with respect to maximum stresses and the amount of wheel load interaction.
