Abstract

To accurately analyze the distortional effects of corrugated steel web composite box girders with mid-span diaphragms under eccentric lane loading, the general solution of the distortional governing differential equation is derived via the energy variational method and expressed using Krylov functions. The anti-distortional effect of the mid-span diaphragm is equivalently modeled as a concentrated distortional moment, yielding an analytical solution for the distortional response. Validation through numerical examples and ANSYS finite element simulations confirms the method's accuracy.
