摘要：
On the basis of frame analysis, considering the effects of the characteristics of corrugated steel web, the distortion of box section, and arrangement of virtual lateral restraint, the analytic formulas of transverse internal force for double-cell Composite Box Girder with Corrugated Steel Webs(CBGCSW) were established, to analyze. the influence of virtual lateral restraint on the transverse internal force of the double-cell CBGCSW, as well as the influence of parameter variation of corrugated steel web thickness, corrugated angle, corrugated length, and the ratio of width to height on the transverse internal force of the double-cell CBGCSW. The results show that the present analytic results agree well with the numerical results from finite element method. Virtual lateral restraint has minor influence on the final calculation results of the transverse internal forces of CBGCSW, with the deviation of the results of less than 2.5%. The transverse bending moment at corners increases with the increase of thickness of corrugated steel web. The variation of corrugated angle has a great influence on the transverse bending moment at corners between bottom slab and side web. With the increase of width to height ratio, the transverse bending moment at corners increases. The increase of the transverse bending moment is remarkable especially with relative large ratio of width to height. © 2019, Department of Journal of the China Railway Society. All right reserved.
