      The design of a runway beam for overhead cranes is of great importance when constructing steel structures, as is the lateral-torsional buckling (LTB) value obtained for I-beam sections. Therefore, engineers must always consider the optimal design of these beams under overhead cranes loads. In this study, runway beams of three overhead crane groups were analyzed for LTB, and a sinusoidal runway beam body was developed. These runway beams with different sinusoidal angles were analyzed by using the finite element method (ABAQUS) and compared to each other and other runway IPE-IPN beam sections; furthermore, all models were compared with the Canadian Institute of Steel Construction standard. As a result, a new method was proposed for developing sinusoidal runway beams for overhead cranes. The sinusoidal runway beam has lower weight than runway IPE-IPN beam sections. Ultimately, a sinusoidal beam body was developed practically with a scale of 1:1.

    • Failure modes of end-plate connections with outer flange stiffeners: an experimental and numerical study


      More Details Abstract Fulltext PDF

      This paper presents the experimental and numerical results of six full-scale beam-to-column connections with bolted end plates in two groups. The effects of vertical and horizontal stiffeners on the static behaviour of the semi-rigid beam-to-column bolted connections were investigated. In addition, the aim of this research was to analyse the influence of end-plate connections that utilize the IPE profile with stiffeners welded on the behaviour of steel connections, to provide the necessary data for improving Eurocode 3, efficient use of residue IPE profiles and back to the consumption cycle. Furthermore, finite-element and experimental models ofsemi-rigid vertical and horizontal stiffened bolted connections were tested and compared. The main parameters observed are the evolution of the resistance, the stiffness, the rotation capacity, the ductility of a joint, failure mode and the energy dissipation.

    • Influence of beam/gusset plate thicknesses on the moment–rotation capacity of cold-formed steel screwed back-to-back sections


      More Details Abstract Fulltext PDF

      The influence of the moment–rotation characteristic on cold-formed steel (CFS) screwed back-toback sections with varied beam and gusset plate thicknesses is investigated in this work. Twelve full-scale studies were used to determine their behavior. The results reveal that the moment resistance values increase indirect proportion to the thickness of the beam. In addition, the ratio of beam thickness (‘‘t’’) to gusset plate thickness (‘‘tp’’) is critical in calculating rotation capacity, energy dissipation values, and cost-effective design. The ductility of the joint values is also affected by the thickness of the gusset plates. Furthermore, the failure modes of the all-specimens tests show that the gusset plate thickness can be reduced to make the system more cost-effective.
