Research on Bending Performance of Continuous Composite Girder Bridge with Corrugated Steel Webs

Abstract

Corrugated steel webs have crinkled effect without capacity bearing the axial force and bending moment, which leads to its effective elastic modulus is smaller than that of material. This paper deduced the computational formula of effective elastic modulus corrugated steel webs, and puts forward the calculation method for corrugated steel webs of composite beams. Combined with a continuous composite box-girder bridge with corrugated steel webs, the finite element model is built to analyze the bending performance such as normal tensile stress, normal compressive stress and crack resistance.
