· As a general rule for the Houston area, material costs are about $.90 per sq. ft. of floor (with trusses 24 in. o. c.). If the job is a long way from the manufacturer, shipping can increase the costs significantly. A joist floor system, on the other hand, costs about $.85 per sq. ft. of floor. This means that material costs for a truss floor

· Girder truss is a kind of high-performance truss, which is combined with some single trusses by connectors. It is the common structural form of the key-bearing node in the modern wood structure floor and roof structure system.

· PDF A truss can be defined as a beam with an open web, formed by a triangulated arrangement of linear elements. A typical arrangement of a truss is shown in Figure 1.1. This arrangement has parallel ‘chords’ (equivalent to flanges) and the ‘web’ is provided by a mixture of ‘diagonals’ and ‘posts’ or ‘verticals’ (at right angles

To frame this style roof, hip trusses are utilized from the main peak of the building, stepping down with a flat top chord. The flat portion is increased the nearer the truss is to the end wall. A “hip set” is then used to frame the 6 or 8 feet nearest the end wall.

Vierendeel trusses are rigidly-jointed trusses having only vertical members between the top and bottom chords. The chords are normally parallel or near parallel.

A parallel chord truss is different from most other timber frame trusses in that it is not triangular in shape. They have a rectangular design, with the top and bottom chords (the long straight elements of the truss) strengthened and spaced by intermediate elements called webs.
