| Abstract: | Based on the theory of three-dimensional transient temperature fields and the finite element software (ANSYS), a finite element model for calculating temperature field and temperature stress of massive concrete is created. This paper makes simulation analysis and calculates the concrete temperature fields and temperature stress of 3# main pier of Ye Sanhe Bridge in Hubei. It also compares the calculation results with those by the field measurement. The results demonstrate that the finite element model can effectively analyze the temperature fields and stress in concrete construction. |
