摘要：
A new model of describing the shear lag phenomenon in thin-walled beams with arbitrary open or closed cross-sections is defined on the basis of the warping function proposed by Prokic. The general approach to the solution of the problem is based on the finite element method. The principle of virtual displacements has been used to give a new linear stiffness matrix. The method is illustrated by examples. (C) 2002 Elsevier Science Ltd. All rights reserved.
