Abstract

Abstract

The webs and bottom slabs of traditional concrete box girder were optimized, and a new structural type of fabricated bridge named RCFST (rectangular concrete filled steel tubular) composite truss bridge was proposed. The structure design optimization procedure was introduced from the aspects of general design, main truss selection, cross section selection, bridge deck slab selection, member bar selection, joint selection and connection structure. The RCFST composite truss bridge was analyzed by finite element method from the static mechanical property and seismic response of the bridge, and the effective width and mechanical property of bridge deck slab in the negative moment zone of the slab. The partial composite technique wasalso used in the design of bridge deck slab connector in the negative moment zone. From the technicality and economy, the RCFST composite truss bridge was compared with the prestressed concrete box girder bridge in terms of engineering quantity and construction convenience. Analysis result shows that the selection of RCFST composite truss bridge structure meets the industrialization requirement of bridge's prefabrication and accelerated construction, and the member bars of main truss with clear force-bearing states mainly carry axial tensions and pressures. The effective width coefficient of bridge deck slab in the negative moment zone is 0.899. The axial tension of bridge deck slab decreases by 75.3% using the partial composite technique, which effectively improves the anti-crack ability of bridge deck slab. The initial input earthquake load of RCFST composite truss bridge accounts for 58.9% of the load of prestressed concrete box girder bridge with the same span, which indicates RCFST composite truss bridge has good anti-seismic property. The ratios of steel quantity, concrete quantity, and superstructure self-weight of RCFST composite truss bridge to prestressed concrete box girder bridge are 1.241, 0.485 and 0.575, respectively, which indicates the RCFST composite truss bridge has good economic advantages, such as simple structure, high utilization of materials and low building cost.
