| Abstract: | The crack causes,which resulted in mid-span vertical cracks of beam side and level cracks of beam bottom of a RC frame structure,are analysed in this paper through four aspects of design,material,construction and use.Surface treatment method and sticking carbon fiber method are presented to reinforce and repair cracked beams.The precausion measures of such cracks are proposed,which provide reference for similar problems. |

| Keywords: | frame beam crack shrinkage cover precaution measures |
