| Abstract: | Based on the non-adiabatic temperature rise test of concrete cuboid at the field laboratory and the 3-D finite element method of concrete temperature simulation,and by using RAGA in back analysis of the concrete thermal parameters,good result is achieved.As one kind of optimization,RAGA are simple and universal and also have the characteristic of good adaptability.The back analysis result shows the fast convergence and high efficiency of RAGA in the back analysis of concrete thermal parameters. |
