1 2 3 4 5 6 7 8 3.23 FLOOR TRUSS SYSTEMS Configurations TrusSteel open web floor trusses are fabricated with the same materials used in TrusSteel roof trusses. The obvious advantage of an open web floor truss over conventional joist framing is the ease of equipment installation for the mechanical, electrical and plumbing trades. TrusSteel open web floor trusses may allow greater clear-span capabilities and facilitate a variety of bearing options. Truss depth and on- center spacing will be determined by specific loading and span requirements. Serviceability Serviceability parameters are specified by the building designer and then trusses are designed accordingly. In order to ensure a rigid floor system, TrusSteel recommends a minimum live load deflection criteria of L/360; more rigid requirements may be specified. All TrusSteel floor trusses are recommended to be fabricated with a minimum of two patented Double-Shear fasteners at all web-to-chord connections to ensure rotational stability of the web and increase product stiffness. Girders Multiple ply girders at stairwells and other openings allow TrusSteel to provide the entire floor framing package. These girders are designed to carry concentrated loads at specific locations and must be installed according to approved shop drawings. Standard connection details are provided with the truss package to ensure proper installation and load transfer. Truss bears on support member at the truss heel. Continuous strongback bracing provides stability and reduces dynamic response of truss system. Duct work runs through optional integral chase opening created in truss webs. Truss girder (two-ply girder shown) supports other CFS trusses. Typical Floor Truss System TrusSteel floor trusses provide the convenience of open web members. Note: Truss bracing not shown for clarity. ENGINEERED BY ALPINE S P E C I F Y I N G / D E S I G N I N G
