| Abstract: | Based on ANSYS,a well known FEM software,a 3-D finite element calculation model for temperature field analysis in concrete filled rectangular steel tube column was built to simulate a steel-concrete bent column for the powerhouse of a hydropower station.With the present model,the regularities of temperature and stress variation in the rectangular column were analyzed under the conditions of temperature rise and temperature drop,the characteristics of temperature distribution in the concrete column in fire were discussed,and the effects of two different boundaries on the thermal stress in the concrete column were compared.Analysis shows that the calculated results accord with the reality of the project. |
