Therefore, it is necessary to know the main method that box girders exchange heat with the external world, the assumption that can meet need of engineering calculation and a clear boundary condition of all the surface of box girders.
Calculations in this chapter have fully prove that the finite element software to solve complex engineering problems have greater advantages and enough accuracy to meet the requirements of engineering.
