Temperature Field Calculation and Influencing Factors Analysis for Concrete Hollow Piers Under Solar Radiation

摘要

The temperature field of concrete hollow piers under solar radiation was simulated by the FEM (Finite Element Method) analysis software and the simulation was compared with the test data. Meanwhile, the factors influencing temperature field of hollow piers were analyzed by considering the maximum temperature on external surface computed from different geographical location, heat conductivity coefficient and atmospheric transparency. Results indicated the simulation was reliable to meet engineering needs. And the analysis gave the change rules of temperature field.
