Experimental Stress Analysis of Cast In Situ Concret Roof-Slab under Indirect Load of Variable Temperature
An electrical experiment on the full-scale model is conducted. Distribution of temperature stress and strain for the cast-in-site concrete roof slab during typical time of extreme weather in the winter and the summer are obtained. Cracking mechanism of cast-in-situ concrete roof is revealed preliminary. Contrasting of the experimental data between the green roof and bare plate roof plate ,it is expounded that planting roof can reduce temperature difference and average variable temperature for the roof slab significantly.
