A COMPUTER PACKAGE FOR STRUCTURAL ANALYSIS OF CONCRETE PAVEMENTS

Abstract

A computer package based on the finite element method was developed for the structural analysis of concrete pavements. The package can be applied to multiple jointed slabs on a liquid, solid or layer foundation. The procedures for developing the package are presented and its capabilities and limitations described. Salient features of the package include the development of an iterative method to reduce the computer storage, the analysis of partial contact by a method of successive approximation, and the consideration of shear and moment transfer across the joints and the looseness of dowel support. Examples are given to illustrate the application of the package to the analysis of concrete pavements.
