Abstract

Shear strength of trapezoidal corrugated steel webs is an important issue for the design of box girder bridges with trapezoidal corrugated steel webs. In this study, a shell element FE model of trapezoidal corrugated steel webs is firstly built for the further analysis of shear behavior. Extensive parametric studies based on the linear elastic buckling analysis are then conducted to propose an appropriate formula for calculating the elastic shear buckling strength. Furthermore, the nonlinear buckling analysis is conducted to intensively investigate the shear strength associated with initial geometric imperfections, and the formulae of the shear strength are proposed. Good agreements can be observed between the results calculated using the proposed prediction formula and the experimental results.
