Design and investigation of girders made of rolling sections with i-top chords

Abstract

Girders made of rolling sections with I-top chords and grating made of equiside angle bars are studied. The purpose is to develop the structural approaches, the design technique and the recommendations for roofing designing by using the girders made of rolling sections with I-top chords. A design model for the girders is validated experimentally. It is calculated theoretically that the loss of resistance on bending and torsion controlls the top chords and the main relationships of the critical stresses are determined. A new type of light metalworks and recommendations for designing and design technique of the girders made of rolling sections with I-top chords are developed. The results from the work have been used for the development of the type diagram manual on the girders made of rolling sections of the series 883665KM and for the quantity production of the girdersAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
