STRUCTURAL OPTIMIZATION ANALYSIS OF HIGHRISE BUILDING BY USING THE THIN-WALLED BEAM THEORY CONSIDERING SHEAR EFFECT : Study on structural analysis of a high rise building by the thin-walled beam theory (Part 3)

Abstract

In this paper, we present a generalized formulation of thin-walled beam theory considering the effect of out-plane distortion due to shear in flexural-torsional problems. By using the finite element method based on this theory, the shear-lag effect of the beams with general shaped cross section can be analysed accurately. By the application to the structural optimization analysis of highrise building, the accuracy and efficiency of this method is verified.
