Abstract: 

Heat transfer theory for concrete tower of cable-stayed bridge will be the basis of the temperature field analysis using the finite element method analysis of the stress field of indirect coupling, accurate analysis of the internal structure of the transient temperature and stress field stacked Jiahousuota stress distribution. In real bridge, for example, solving the temperature stress on the tower, and demonstrated: Solving transient temperature field finite element method can accurately simulate the temperature distribution in Sarasota; the treatment temperature change methods - mechanical coupling problem, can temperature load and other effective combination of load stress field, resulting in accurate stress distribution in the structure.
