Steel Buildings1.1 SCOPE 1.1.1 These specifications cover the materials and the fabrications of the prefabricated steel building system design. 1.1.2 These specifications are an outline of performance to insure that the architect, engineer and/or metal buildings owner understands the basis for design, manufacture and application of the manufacturer's steel buildings systems. 1.1.3 Because of a continuing program of research and development, specifications are subject to change without notice. 1.2 STEEL BUILDING DESCRIPTION 1.2.1 Rigid Frame, Clear Span (RF) is a continuous, frame steel building with variable depth or uniform columns and rafters. It is double sloped with a standard roof pitch of 0.25:12 to 4:12. Sidewall girts are by-pass or flush. Endwall girts are flush. 1.2.2 Taper Beam, clear span (TB) is a continuous frame steel building with uniform depth columns and variable depth rafters. It is double sloped with a standard roof pitch of 0.25:12 to 4:12. Sidewall girts are by-pass or flush. Endwall girts are flush. 1.2.3 Multi-Span (MS) is a continuous frame steel building with variable or uniform depth columns and rafters with one or more interior columns. It is single or double sloped with a standard roof pitch of 0.25:12 to 4:12. Sidewall girts are by-pass or flush. Endwall girts are flush. 1.2.4 Lean TO (LT) is a steel building extension, which depends on another structure for partial support, clear or multi-span with uniform or variable depth columns and rafters. It is single sloped with a standard roof pitch of 0.25:12 to 4:12. Sidewall girts are by-pass or flush. Endwall girts are flush. 1.2.5 Single slope (SS) is a continuous frame steel building, clear or multi-span with uniform or variable depth columns and rafters. It is single sloped with a standard roof pitch of 0.25:12 to 4:12. Sidewall girts are by-pass or flush. Endwall girts are flush.
1.2.7 Roof Systems (RS) is a simple beam clear or multi-span, masonry supported, roof only structure with uniform or variable depth rafters. 1.3 BUILDING NOMENCLATURE 1.3.1 Roof pitch is the ratio of roof rise in inches to 12 inches of horizontal projection of the roof. 1.3.2 Bay spacing is the distance from centerline to centerline of adjacent frames. 40' is the maximum bay spacing, 20 and 25 feet are standard. 1.3.3 Steel Building width is the measurement from out to out of sidewall girts. 1.3.4 Steel Building length is the measurement from out to out of endwall girts. 1.3.5 Steel Building height is the measurement from bottom of column base plates to the top of eave strut. 1.4 DRAWINGS & CERTIFICATIONS 1.4.1 The steel building manufacturer shall furnish a complete set of erection drawings for proper identification and erection of all steel building components. Drawings shall show anchor bolt settings, transverse cross sections, sidewall, endwall and roof framing and installation details. Drawing shall also show sheeting, trim, and accessories installation details. 1.4.2 Steel Buildings components shall be factory piece marked for easy field identification. 1.4.3 Drawings shall bear the
seal of a registered professional engineer. Design analysis shall be
furnished upon request.
