Webanalysis using ohly temperature effects indicated excessive daytime curling stresses, which would result in maximum tensile stresses at the bottom of the slab. This tensile curling sfress would cause crack initiation at the bottom of the slab and crack propagation from the bottom to the top of the slab. However, cores WebOct 10, 2024 · The maximal stress of each case in a day was extracted, as shown in Fig. 17. From Fig. 17 we can notice that the variation amplitude of tensile stress and compressive stress are both large, but the absolute value of compressive stress is small and that for tensile stress is huge compared to the strength value. In order to avoid large …

WebApr 26, 2012 · Curling generally results from the temperature differential across the concrete slab thickness and may induce undue stresses in newly placed slab.
