| Abstract: | This article includes the designing method and technique which are used in reinforcing concrete slab-column by sticking prestressed CFRP sheets.First of all,author introduced materials and reinforcing manner,then used equivalency frame method to confirm account model and calculateal load and internal force of board based on the normal use ultimate state and carrying capacity limit state.Author confirmed the amount of prestressed CFRP sheets based on the resist crack demand of the normal use ultimate.In the end,calculated expressions of the curved moment and the limit carrying capacity were put forward. |

| Keywords: | Prestressed CFRP sheets reinforce slab-column curved moment limit carrying capacity |
