Design Of Hollow Section Overlap Joints With The Reinforcing Rib Plate. Welded Connection Resistance

“

The method of calculation of the welds’ resistance within the connections between the hollow sections presented in EN 1993-1-8 is very general, and without indicating specific calculation procedures. The publication mentioned in the references contains only fragmentary information in relation to gap joints. In earlier publications the authors presented the procedures for assessing the resistance of fillet welds of T, Y, X and gap K, N types of joints made from hollow sections have been developed. Consequently, the method of design for overlapping K and N joints is also presented. In all these types of joints fillet welds are used, with their effective lengths determined on the basis of experimental research or design guidelines presented in EN 1993-1-8 ,though in the latter, the design of these lengths are not provided explicitly. In EN 1993-1-8 [9] the calculation of the joints with fillet or groove welds with effective weld length is allowed in cases when: the forces in the braces are less than the resistance of the joint, instability of the braces could occur, or when unifying the range of truss elements. Such situations are commonly found and both designers and contractors need to be aware of them. Weld design for hollow section trusses. LAP LAMBERT Academic Publishing.
