Abstrakti

The use of High-Strength Steel (HSS) and novel joints in trusses challenge the applicability of current European standards and stress the need of experimental results. Particularly, the lack of loading capacity required by the HSS member can be a challenge for many test facilities. This study resolves these challenges by a novel welded K-type truss joint made of S420 and S700 steel grades and by the use of dimensional analysis to reduce the size of the test samples. The procedure and results of experimental tests on the joints are presented. The specimens are isolated joints with scaled-down geometries to meet the available loading capacity. The Finite-Element Model (FEM) is created and validated against the test results of the S420- and S700-grade joints. The validated FEM is then used to estimate the failure mode of the S700-grade joints. This FEM is used to study the deformation and failure modes of this truss joint to enhance the design of similar K-type joints in practical design.
