Peculiarities of resistance definition for welded offset T-joint between RHS members

Popis výsledku v původním jazyce

Steel structural hollow sections, including rectangular hollow sections (RHS), are nowadays one of the most efficient load-bearing elements of the lattice structures. Despite its widespread application, there is still lack of design techniques for joints produced with offsets. The article intends to eliminate gaps in knowledge about the mechanical resistance and design of so-called offset RHS joints, welded T-joints composed from rectangular hollow sections with a certain lateral offset of a brace from a centreline of a chord, under brace axial compression. The paper presents results of numerical investigations of structural behaviour of the mentioned joints in comparison with existing analytical methods of connection nominal resistance determination for both standard (co-axial) and offset welded RHS joints. For validation purposes, the full-scale laboratory tests were conducted. Numerical models were created using a general FE programme Abaqus and a component-based FE programme IDEA StatiCa. Particular attention was given to mesh size effect and weld seam modelling. The curve fitting analytical model complying to prEN1993-1-8:2020 proposed by Wei and Packer [1] is verified by numerical experiments. The limits of validity of considered analytical model are examined and proved by calculations.
