Abstract: In order to research the effects of temperature load acting on solid concrete pylon, a calculation method was put forward based on the fundamental principles of the heat transfer theory. In this method, initial conditions are determined by means of applying periodic load, and boundary conditions are ascertained from the thermal equilibrium on the surface. By taking a certain bridge as an example, the short-term temperature characteristics of H-shaped section concrete pylon were analyzed by using indirect temperature-stress coupling finite element method, and the distribution features of temperature field and thermal stress were obtained. The analysis result indicates that under the most unfavorable short-term temperature load, temperature cracks may appear on the surface of H-shaped section concrete pylon, so a special attention should be paid to design.
