- Abstract
Steel roof trusses are a frequently used element for carrying roof cover in industrial type structures. Roof trusses are generally preferred for long spans that cannot be designed with standard sections. These load bearing members can be created using many different types of mesh. In recent years, it has been observed that there are damages in the steel roof trusses due to heavy snowfall, especially in industrial buildings. Therefore, it is important to design these members safely and economically. In this study, roof trusses with 24 m span, 0.8 m side and 3.2 m ridge height were investigated for 5 different mesh types. A total of 20 analyses were performed for 4 different purlin distances using the SAP2000 program. Specification for Structural Steel Buildings (AISC 360-16) published by The American Institute of Steel Construction was used for the member design of these 20 roof trusses, whose external geometric dimensions are the same. As a result, the most economical roof truss type and purlin distance were determined by comparing the roof truss and roof truss + purlin weights obtained from the design. Minimum cross sections and minimum total weight were obtained for Warren truss mesh type with 2.4 m purlin distance.
