The steel roof structure is loaded with force effects that take into account weight of the roof structure, the weight of the roofing, the snow load and the weight of the air conditioning. For the loaded roof structure, a stress analysis is performed using the finite element method, from which the stress fields and the size of the axial forces in rods of the roof structure are obtained. These axial forces strained the riveted elements and can also cause the buckling of the longest and the most stressed rods. For this reason, a check is carried out on the riveted elements at the most stressed places of the structure, and a check is then carried out on the strut. It is clear from the results that all the riveted elements are suitable, and there is no loss stability of the rods. http://pubs.sciepub.com/ajme/5/6/20/ajme-5-6-20.pdf riveted joints rod linear buckling strength truss roof
