Abstract:This report summarizes the work in Research Project 3-5-63-56 which has been conducted by the Center for Highway Research. The project staff has produced 27 research reports dealing with the analysis and design of structural members including beam columns, grid-beam systems, slabs, and slabs on foundation. This report summarizes the portions of the work which are directly related to the analysis and design and of pavement slabs. The details of the discrete element methods outlined herein may be found in the individual reports which are referenced. A wide variety of variations of the basic slab methods have been developed including (1) variable increment length capability, (2) multiple loading analyses, (3) dynamic loading considerations, and (4) handling of skewed slabs. The methods have been verified by comparison with closed form solutions and with various small dimension tests. The results have been applied in numerous forms by the Texas Highway Department including the development of design charts, analysis of special problems, and the analysis of field data.
