Elastic analysis of curved thin-walled girders including the effects of warping restraint
Abstract Various geometrical and sectorial functions are derived to described the transverse distribution of stress in curved, thin-walled box girders subjects to generalized loading. Member curvature and secondary shear effects are fully considered. From a general expression for strain energy, the member flexibility matrix is derived explicitly in terms of girder geometry. This enables indeterminate structural systems incorporating curved, thin-walled members to be analysed by the compatibility method. The approach is demonstrated by the analysis of a circular curved girder fully fixed at both ends and loaded at its centre. Numerical examples are presented for some typical girder configurations.
