ABSTRACT:
A structural bar comprises two chords and an upright web interconnecting such chords. The web is shaped trapazoidal with bulges extending alternatingly to the one or the other longitudinal side or rim of the structural bar. Any kinks or breaks of the trapezoidal shaped web are avoided. The chords are connected to the edges of the web or webs by means of continuous weld or by welds of limited length which provide in total a continuous weld line at least in the longitudinal direction of the structural bar. Thus, the load capacity or supporting capacity of the structural bar can be determined exactly so that over-dimensioning is to be avoided.
