Abstract

This paper presents a three-dimensional analysis of tall building structures using an improved continuous medium technique model in which consistent global column bending and column longitudinal deformation are considered along with a decoupling technique for the resulting system of differential equations. A numerical example shows that although the proposed methodology is very simple and suitable for hand calculations, it presents very good accuracy in comparison with finite element method computations.
