Abstract

Treatment schemes are put forward to solve the problems which exist in prestressed concrete crane girders according to real work condition.Through comparing and selecting the initial treatment schemes,sticking to CFRP sheets is chosen to strengthen crane girders.It is introduced that the design points and schemes to strengthen fish-bellied T section prestressed concrete crane girders using CFRP sheets, including the calculating methods of bending and shear bearing capacity as well as strengthening construction program.The examination shows that the technical indices of the crane girder strengthening meet the demands on design. The research results can be a reference in theory and method for the similar engineering.
