Abstract

Failure of structures associated with repeated moving surface loads are typically caused by gradual deterioration rather than sudden collapse. This type of failure behavior is mostly due to the accumulation of plastic strains under repeated loadings. They are different from the solution of most stability problems under simple loading programs. This paper aims at presenting a general numerical method for the shakedown solutions of pavements subjected to repeated moving traffic loads. To achieve this goal, a novel numerical formulation based on Bleich-Melan shakedown theorem is developed by making use of finite element techniques and mathematical programming. The proposed numerical procedure will be used to solve for the shakedown limit load and the associated developed residual stresses in layered materials.
