Effect of Different Steel Sections on Design of Roof Truss

Abstract

Roof trusses, which are structural components of houses or commercial buildings, support the weight of roof purlins and coverings. Roof truss is mainly used in parking sheds, industrial buildings, warehouses etc. In present study, a comparison is made out between the mass of truss using steel single angle, double angle, tubular and pipe sections. Truss span chosen is 10 m with recommended rise of 2 m. The wind zone, permeability, column height, truss spacing and topography are considered and kept constant. Analysis and design of selected truss profile is carried out with the aid of software STAAD Pro v8i 2007 and designed according to IS800: 2007 LSD. This study gives us the idea of section to be used in designing with economic point of view.
