Abstract:Combined with the project design practice of a reinforcing reform of a steel structure workshop, the method of checking calculation and structural strengthening design of crane girder and steel structure of light-weight building with gabled frames for crane capacity increasing were discussed,the method of enlarged cross section was used to reinforce the steel crane beam and steel bracket, foundation strengthening with encircling reinforced concrete method was used to consolidate the spread foundation under column, and smoe issues need to be attented in the reinforcement and transformation design were put forward.
Keywords:structure strengthening; increasing section method; foundation strengthening with encircling reinforced concrete; steel crane girder; steel corbel; spread foundation under column
