The purpose of the research is: on the basis of a comparative analysis of geometric characteristics to conclude that the advantages of using in the construction of truss rods of pentagonal cross-section instead of rectangular and square. To develop a computational model of a shapeless joint of pentagonal truss rods, which would scientifically substantiate the use of shapeless joints in the structures of trusses of small and medium spans - in contrast to the shaped joints used traditionally. To develop scientific bases of designing of metal trusses of folded coverings of small and average spans with high operational properties. Set the optimal shape popup.nrat_date 2024-12-10 Close
