ANALYSIS OF PIN-JOINTED SPACE FRAMEWORKS: NONLINEAR EFFECTS.
Abstract
Structural analysis of pin-jointed frameworks with large deflections is carried out by postulating 'fictitious forces' and 'fictitious thermal strains' depending on the joint deflections and member loads. These fictitious quantities are added to the actual applied forces and thermal strains to obtain a corrected solution. The first part of this report discusses the analysis of space frameworks in the manner of conventional matrix structural analysis. The second part considers the general nonlinear behavior of such structures using a virtual displacements approach and by retaining the second order quantities justifies the use of fictitious forces and strains. The equations of elastic stability are also derived. (Author)
