Piers attacked by a cold wave, often exhibit uneven temperature distributions, which are direct causes of temperature effects in concrete structures. In order to investigate the influence of cold waves, a three-dimensional transient thermal-structural coupled field method was implemented in a finite element software ANSYS to analyze the temperature filed of concrete hollow pier under a cold wave first. The validity of the finite element (FE) model was verified by the experimental results. After that, the FE model was extended and used to simulate the temperature field and thermal stress of a cylindrical hollow pier under the cold wave. The results show that the circumferential stress under the cold wave is large, and therefore it needs to be considered in the cylindrical concrete hollow pier design.
