This example outlines a comprehensive procedure for designing a standing seam roof system and applies to both the panel and its supporting purlins. Table values based on Grade 50 material are differentiated with bold-faced type and shading.įour new example problems have been added:ġ) Four span continuous standing seam roof system

Similarly, tabulated strengths for Grade 33 are provided for sections with a thickness less than or equal to 43 mils. Tabulated strengths for Grade 50 are provided for sections with a thickness greater than or equal to 54 mils.

The strength tables for joist/stud and track sections have been updated and reflect only the thicknesses readily available for each steel grade. The introductory sections have been updated to include expanded discussions on cold-formed flexural member behavior and limit states, including distortional buckling, in order to assist in an overall understanding of cold-formed steel beam behavior and design. This example illustrates the application of the new design provisions of AISI S100-12 Section B2.5 for determining cellular deck effective section properties. This example illustrates the effect of large corner radii on effective section properties by using the rational engineering method provided in Section B1.3 of the AISI S100-12-C Commentary.Ģ) Effective section properties of cellular deck with intermittent fasteners between deck and cover plate The effective section property examples have been updated to reflect changes in Chapter B of AISI S100-12.ġ) Effective section properties of a panel section with large radii Similar to the previous edition of the Manual, formulas for calculating gross-section properties used for compression or flexure, and the properties for distortional buckling analysis, have been provided for commonly used C-, Z- and Hat-Sections. The cross-sections provided in Part I include: “representative cross-sections,” such as purlins or girts and light-steel framing cross-sections (joists, studs, or track). Information regarding steel deck products has been updated to reflect the latest requirements published by the Steel Deck Institute (SDI). The table of referenced ASTM steels has been updated to reflect recent changes in steels approved for cold-formed steel design. AISI Manual for Cold-Formed Steel Design Dimensions and Properties
