| Abstract: | The calculation model and differential equation of axial tension component were built under the action of thermal difference and difference of the linear expansion coefficient between the steel and the concrete. The solution of differential e-quation was given. Distribution regulations of stress and displacement under the action of thermal difference were analyzed. The effects on the displacement and stress causing by distance between cracks, the reinforcement ratio and the thermal difference were analyzed. |
