validated against in-situ data from site instrumentations. Good agreement was obtained for
thermal flow models, and the negative impact of air movement over the top of the slab has
been highlighted. Plane stress models of slabs exposed to uniform and differential thermal
gradients representing hydration and shrinkage effects demonstrated that the stresses resulting
from frictional restraint are significantly less than those caused by warping restraint, even
though the latter are currently not considered in design.
