Abstract EN
The structural optimization method of steel cantilever used in concrete box girder bridge widening is illustrated in this paper.
The structural optimization method of steel cantilever incorporates the conceptual layout design of steel cantilever beam based on the topological theory and the determination of the optimal location of the transverse external prestressed tendons which connect the steel cantilever and the box girder.
The optimal design theory and the analysis process are illustrated.
The mechanical model for the prestressed steel cantilever is built and the analytical expression of the optimal position of the transverse external tendon is deduced.
At last the effectiveness of this method is demonstrated by the design of steel cantilevers which are used to widen an existing bridge.
