An improvement in the art of bowstring roof truss construction comprising an altered web pattern in which the diagonal and vertical webs, normally converging at points alternately within the geometric confines of the top chord and the bottom chord, intersect or converge rather at points intermediate between top and bottom chord on massive vertical webs. This system facilitates more head room and walk-through space where a tributory floor is framed into the bottom chord of the truss. This system comprises (1) an arched top chord with intersecting vertical and diagonal webs, (2) displaced intersection points of the diagonal webs onto the massive vertical webs, (3) a suspension assembly to hang the bottom chord using direct bearing and (4) a separate assembly to transmit the longitudinal truss-action forces from the vertical webs to the bottom chord. |
