This paper covers design and analysis of steel roof truss and their importance for the structural systems used in steel structures, mainly for roofing and other long-span applications. The paper specifically looks at performance aspects of angle sections as purlins, as well as comparing these with hollow sections. The modelling and analysis of steel roof truss done by STAADpro. Calculation of truss behaviour subjected to dead loads, live loads, wind load, seismic load considering factors such as buckling, stress distribution, and deflection. The code IS875 -1987 PART-1 used for finding design loads. The main aim is to find load-carrying capacity, weight efficiency, cost-effectiveness of the two types of members under regular loading conditions. A careful comparison between these two types of members is given by considering several design criteria such as ease of fabrication, availability of the material, and long-term durability. This analysis eventually optimizes steel truss designs and provides useful insight for the structural engineer to choose the appropriate purlin for a particular application.
