Title of the articleThe load capacity of joint of the truss made by typical blueprints 1.460.3-14КМ
Abstract.This article reviews the different approaches in estimate of load capacity of the welded joints in steel truss made from rectangular hollow sections. The load capacity calculated accordingly by Russians code does not consider some aspects that could be faced in designing of steel trusses made from rectangular hollow sections. Especially it does not certainly point, in case when into joint one brace element is compressed and other does not care load, should joint be considered as a K-joint or a Y-joint type. The difference in load capacity between K and Y-joints with compress brace member is more than 30 %. These limitations could have caused collapse roof elements in some parts of building of warehouse «Biek-tau» that has place in Kazan suburbs in 2011. Also computational researching with engineering software was held it has shown that in this truss the moderate joints inside non moment zone (joints near center of span) should be considerate as Y-joint type despite the shape of joint which looks like a K-joint type.
Keywords.Rectangular hollow sections, K-joint, Y-joint, the load capacity of the joints.
