Summary

In this paper a general formulation for the nonuniform shear warping analysis of composite beams of arbitrary simply or multiply connected monosymmetric cross section, with general boundary conditions is presented. The beam is subjected to the combined action of arbitrarily distributed or concentrated transverse loading passing through the shear center of the cross section, as well as to bending moment. The nonuniform warping distribution is taken into account by employing an independent warping parameter multiplying the shear warping function, which is obtained by solving the corresponding St. Venant problem of uniform shear. Three boundary value problems are formulated with respect to the displacement and rotation components as well as to the independent warping parameter and solved using the analog equation method, a boundary element method based technique. The warping function and the geometric constants including the additional ones due to warping are evaluated employing a pure boundary element approach.
