| Abstract: | Due to the flaws of design and construction in cantilevers,test inspection,appraisement and strengthening of the structure are made in order to remove safely hidden trouble.According to actual requirements,some strengthening methods such as steel tie rod,sticking steel,steel brace and steel bearing are chosen to reinforce the cantilevers.The design process that the cantilevers are strengthened by the method of steel tie rod is introduced in detail. |
