Ultimate Strength of K‐joints in Lattice Structures Composed of Circular Hollow Sections (CHS)
This paper deals with the analysis of the design resistance of joints in lattice structures composed of welded circular hollow sections (CHS). The analysis was carried out on a K‐joint. Determination of the design resistance of lattice structures is based on the calculation of design resistance of compression members in uniform compression, taking buckling into account, in accordance with EN1993‐1‐1 and the calculation of design resistance of joints in lattice structures in accordance with EN1993‐1‐8.
The value of the design resistance of compression members in uniform compression is obtained through new diagrams for the resistance of members used for determining the value of compression members' design buckling resistance for a given buckling length of a member.
Calculation of resistance of brace members in K‐joints of a welded lattice structure composed of circular hollow sections (CHS) in accordance with EN1993‐1‐8 is analysed both according to the equations given in the adopted standard and according to the equations given in the new proposal for EN 1993‐1‐8.
Through a comparative analysis of these two criteria, using appropriate diagrams, a simple procedure was given in order to calculate and determine whether the ultimate strength of the brace member was achieved by its buckling or by plastification of the chord member of the joint. The suggested diagrams give an evaluation of the utilization ratios of the adopted members of lattice structures. Provided the sections were properly chosen, it is possible to rationalize the structure.
