| Abstract: |
| The elements stress repair matrix of 8 and 20 similitude parameter node and numerical result have been deduced using the properties of Gauss point,which have high precise value of stress,to improve the node stress in this paper.The coordinate and shape function of Gauss point have also been calculated. |
| Key words: concrete thermal stress stress repair |
