Each of the chords includes an upper chord segment, opposed parallel side walls, inwardly extending lower chord segments, the lower chord segments being parallel to the upper chord segment, and a pair of flanges extending downwardly from the innermost edges of lower chord segments, the flanges defining a longitudinally extending continuous web receiving aperture traversing the length of the chord, the upper chord segment, lower chord segment, parallel side walls and flanges, the web receiving apertures of the upper and lower chords being positioned in opposed relationship. A plurality of web members are provided, each of the web members including an upper web segment, the width of the upper web segment being equal to the width of the web receiving aperture, opposed parallel side walls extending perpendicularly from the upper web segment, and inwardly extending lower web segments, the inwardly extending lower web segments defining a longitudinally extending slot, each of the web members having first and second ends received in the web receiving aperture. A saddle is provided for positioning the joists, each saddle having an upper saddle member, opposed parallel side members and outwardly extending bearing plates, the outwardly extending bearing plates being parallel to the upper saddle member, the upper chord of the joist receiving the saddle in the member receiving aperture at opposed ends of the joist to support the joist.
