A COMPUTER PROGRAM FOR SLABS WITH DISCONTINUITIES ON LAYER ELASTIC SOLIDS

A finite element method programmed for a highspeed computer is presented. The method is based on the classical theory of thin plate. The program is developed for a subgrade soil represented as a linear layered elastic solid. Any number of layers can be accommodated. The program is capable of analyzing stress conditions in concrete pavements with the load transfer in the joint, as well as in the supporting subgrade soil, subjected to loads and temperature warping. Multiple-wheel loads can be input and the number of wheels is not limited. Because of the large computer storage space required, the program can handle only two slabs, except for the special option where a four-slab pavement system is loaded symmetrically at the pavement's center. At the joint, the program considers only the shear transfer and assumes the moment transfer to be zero. The results computed using the program were compared with stress transfers across the joint measured in airfield test pavements. The comparisons were very favorable. (Author)
