Abstract
A joist girder construction includes connecting ties which connect adjacent ends of joist girders at a point where they are supported. The ties include a non-welded zone to afford plastic elongation of the tie. The ties create an axial connection force between the top chords to reduce the force a load causes within the joist girder to thus reduce the size of the upper and lower joist chords to minimize overall weight and expense.
