Analysis of Thin-walled IVSember with Taking into Account the Shear Deformation

In this paper, based on the principle of potential energy the shear lag phenomena of thin-walled members is discussed. Taking the lateral displacement of the cross section and the longitudinal displacement of nodes as the basic variables the finite element analysis of thin-walled member structures is formulated. Numerical examples show that quite good results can be obtained. The proposed method is particularly suitable for the analysis of tall buildings and bridge structures.
