The temperature distribution is strongly nonlinear in thi k on rete slabs, whi hresults in higher tensile stresses at the top of the slabs. This nonlinearity is not taken into a ount in thepreviously proposed thermal stress equations. In this study, a 3DFEM program Pave3D was employedto al ulate stresses under a ombination of nonlinear temperature distribution and orner loading. Thesimulation results show that the tensile stress at the top of slab is greater than simple addition of thermalstress and loading stress that are separately estimated.
