Parametric analysis of axially loaded RHS gap K-joints by means of 2-D and 3-D F.E. models

Abstract

In the present paper the behaviour of steel structural RHS gap K-joints under static loading is studied by applying the Finite Element Method. The analysis is performed by the development of both 2-D and 3-D models of gap K-joints, thus investigating the influence of certain geometrical parameters into the strength and the overall stability of the joint. The geometry of the analyzed joints is in agreement with the general requirements of the EC3. The obtained results are compared to those obtained using the EC3-Annex K calculation formulas and the respective conclusive remarks are presented in the last part of the paper.
