Use of optical-interferometric method to analyze roof elements mutually connected by linear hinges is discussed. Both the warping of the section (due to combined bending and torsion) and plane cross-section deformations by two different theoretical approaches ('rigid section' and 'deformable section') are considered, so that experimental and theoretical results can be compared; a linear load is applied to each hinge in turn.

Abstract
Use of optical-interferometric method to analyze roof elements mutually connected by linear hinges is discussed. Both the warping of the section (due to combined bending and torsion) and plane cross-section deformations by two different theoretical approaches ('rigid section' and 'deformable section') are considered, so that experimental and theoretical results can be compared; a linear load is applied to each hinge in turn. The effects of diaphragm spacing on the section distortion are analyzed in the case of a single prismatic element.File in questo prodotto:
