The paper reviews the typified designs of steel roof trusses of SP-38(S&T); Handbook for typified designs for structures with steel roof trusses having comparison of its design with the values obtained by calculations as per provisions of IS Code IS 875-1987. The paper is related to the analysis of wind load on structural members of industrial shed structures. The analysis of truss is done for different factors of terrain categories, class of structure, topography, height & structure size, permeability condition and calculated wind loads as per provisions of current Indian Standard Code. The paper presents comparative results of the analysis to get the optimum design of steel roof truss or industrial shed structure incorporating various factors, which helps to get economical sections or members of the steel roof structure to enhance the effectiveness of the structural design and its economy through saving of material by optimization. The paper explores the scope of improvisation in typified designs given in the handbook and suggests to incorporate these factors as per current Indian Standard Code to provide typified designs of common forms of industrial structures used in light engineering industries, warehouses, workshops, storage sheds and to obtain economical designs under these conditions.
