Abstract

In thin-walled beam theory the kinematics of the beam is described by 6 degrees of freedom for a rigid body displacement of each cross-section plus an additional degree of freedom for cross-section warping. Torsion and warping are coupled, and this coupling requires special attention at joints. In general the transfer of warping through a joint will create deformation of the cross-section. Although distortion in the form of cross-section deformation is not accounted for in classical thin-walled beam theory this effect is often local, and for cross-sections containing two main flanges — such as I, U and C-profiles — simple joint models compatible with classical thin-walled beam theory can be developed.
