The three … WebDerivation of Curling Stress Equation The variables that affect curling stress were found to be the tem-perature difference, width and thickness of concrete slab, and mod - ulus of subbase reaction. Thus, we assumed a curling stress equation as follows: (14) where σt =maximum curling stress in the transverse joint edge (kgf/cm2); Webslab’s edges on the curling stresses and deflections, which is the main contribution of this study. Maintaining all other Westergaard assumptions unmodified, closed-form solutions for curling stresses and deflections of an infinitely long slab that is partially restrained to displacement and rotation are derived. short african dresses for women
