摘要：

A design method for slabs on grade gives a way to predict the number and size of shrinkage cracks that might appear, depending on the fiber reinforcement, the slab's dimensions and the type of grade. The shrinkage strains are computed with material data such as endogeneous shrinkage, heat oh hydration, drying shrinkage, and environmental data. Moreover, a new parameter is introduced to describe the action of the grade. Then we can evaluate the stress in the slab and explain how fibers can substitute multiple small cracks to one major crack.
