EXPERIMENTAL ANALYSIS OF AN ORIGINAL TYPE OF
STEEL SPACE TRUSS NODE JOINT
Abstract. In the paper is presented experimental analysis of an original type of node joint
for a steel space truss. The joint sample was loaded by spatial set of forces that simulate
real condition of the structure with eight balanced member forces (4 chord and 4
diagonal members), up to structure failure. It was realized in a specially designed test
facility. Tested node joint samples were made in real scale, according to the model
originated after FE analysis and optimization. Basic idea was to construct and test a node
joint that can be made in average technology conditions, without special tools and
requirements. Besides, results of a stress-strain FE analysis are presented and
comparison of the two analyses is given for the most critical regions of the node joint.
Values of measured and calculated strains across model samples and characteristic
measuring points are presented.
