Analysis on the influence of temperature differences affecting on the stress of thin-walled concrete structure

The influence that thin-walled concrete structure suffers from temperature differences is more notable: according to this problem we use the three-dimensional finite element methods to conduct an emulation calculating analysis of the temperature field and the stress field on some thin-walled concrete structure during construction. The result suggests that under the function of day and night temperature differences, there will be more stress fluctuations. This will be harmful in temperature control and crack prevention. So we suggest where there are more day and night temperature differences, the concrete structure during construction should be strengthened on its surface heat preservation or the striking time be extended. These methods can reduce influence the day and night temperature differences have on the structure. The study has more reference values in reality when conducting a concrete construction on the areas where there are more temperature differences.
