| Abstract: | In view of cracks appeared in the connecting point of post shoulder and beam for workshop steel-pipe concrete post in some steel rolling plant,the reason and the expanding cause of vertical cracks in aspect of forming of water-sulphur-calcium aluminate are analyzed,accompanying with expanding stress in concrete,and welding seams design and construction.The preventing measurement for such common failings are proposed. |
| Keywords: | steel-pipe concrete expanding stress circle-reinforced rings |
