Analysis of Thin-walled IVSember with Taking into Account the Shear Deformation
Wu Xiushui (China Academy of Building Research)
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.
