Stress Field Simulation of Concrete Structure Considering Influence of Temperature on Autogenous Volume Deformation

Abstract:

Aotugenous volume deformation is one of the influence factors of stress field of concrete structure. Generally, the influence of temperature on autogenous volume strain is not considered in calculation. In fact, the difference of internal and surface temperature of concrete structure can lead to different hydration reaction and different autogeneous volume deformation. In order to find out the effect of temperature difference on aotogenous volume deformation and stress field of concrete structure, a model is established and a corresponding example is given. The result shows that it is necessary to take temperature effect into consideration while calculate autogenous volume deformation in stress field simulation of concrete structure.
