DEVELOPMENT OF A MODEL FOR STRESS CALCULATION IN ULTRA-THIN WHITETOPPING BASED ON 2-D FINITE ELEMENT METHOD
This paper presents the development of a model for stress computations for 1.20 m wide ultra thin whitetopping (UTW) slabs. The results are compared with previously published models in the literature. The developed model is based on a two-dimensional (2-D) finite element method of structural response analysis. The model shows consistent results when compared with other available 2-D model, especially concerning the effects of the k-value on stresses, pointing out the conservative values obtained from the previous model. Equivalent single axle load factors for UTW are developed, and the use of the traditional fourth power law for UTW is ruled out. The presented model points out the conservative nature of linear load stress relations for designing UTW.
