| Abstract: | Ledu Bridge is a post tensioned prestressed concrete hollow slab beam bridge with 6×20m. The substructure is a four column and four pile type structure. The total width of the bridge is 26.5m and the design loading is Chen A class. In the design the hollow slab beam of the superstructure is further optimized so as to save the material consumption, shorten the working stage and get a good economical effect. The paper introduces the optimum design of the hollow slab beam. |
