Paper Title:
Temperature Field Calculation and Analysis within Steel Tube Reinforced Columns
  Abstract

Theoretical models to calculate the temperature field steel tubes reinforced columns are proposed by finite element program in this paper. The theoretical results are validated by test results, and they have a good agreement. Using the theoretical models, the influencing laws of temperature rising time; section perimeter; steel reinforcement ratio and sectional core area ratio on temperature field are further discussed. It has been found that the surface temperatures of steel tube reinforced columns increase obviously with temperature rising time, and the temperatures of steel tubes and core concrete increase slowly. The effects of sectional dimension and sectional core area ratio on temperature field are significant, but steel ratio has very little effect on temperature both of steel tube and of sectional center. These achievements make it possible to study further theoretical study on the mechanic performance of steel tube reinforced concrete columns in fire.
