![]() ![]() The American Lumber Standard Committee (ALSC) Board of Review has approved changes to design values for all grades and all sizes of visually-graded Southern Pine and Mixed Southern Pine lumber with a recommended effective date of Jto allow for their orderly implementation.ĪWC has developed addenda and other updates to use with new construction designed in accordance with its standards and design tools.ĪWC has also developed recommended amendments to span tables for new construction designed in accordance with ICC model building codes.įor more information, visit. * Qualified students are those who are full-time students enrolled in a wood design course at a university or college.Ģ005 Design Values for Joists and Rafters ABOUT SOUTHERN PINE VALUES (Pricing for Span Tables and Design Values for Joists and Rafters 2005 Combo) This edition has been updated to the 2005 NDS Supplement Design Values. Savings is in the labor.A companion Supplement to Span Tables for Joists and Rafters, Design Values for Joists and Rafters tabulates allowable bending stress (Fb) and elastic modulus (E) values for visually graded and mechanically graded dimension lumber. Then you finish the house like a regular home. ![]() The 2300 sq foot home goes up on the foundation in about 5 days. The spec's were for SPF and they substituted the SPF for SYP, the better wood. Potentially, this is a big problem and you need more info to assure you of the needed quality. Listed are 46 tables based on common loading conditions for bottom truss, ceiling joists and rafters. I would think that you are due a very large discount, and then I still worry about the floor bounce, or else you need to write a letter to the federal trade commission and expose these people for what they are. Simplified utmost span tables with selected visual also mechanical grades starting Southern Pine lumber in sizes 2×4 thru 2×12. The analogy of being shown the Caddy and getting the Geo is correct. The Think Wood initiative aims to project a unified front. Refer to this fact sheet that includes all the information presented here. The life cycle graphic below explains why wood building products are sustainable, responsible and environmentally friendly. But if they used the same size members and same spacing for SPF as designed for SYP, you are getting less than you agreed to and will likely have very bouncy floors, etc. When it comes to green building, wood wins hands down. ![]() If the re-engineering is correct, the floors and roof will be fine with SPF. SPF cannot span the same distance as SYP, so you must have closer spacing, larger sized pieces (2x10 instead of 2x8, for example), etc. If it is for joists and rafters, big difference. Listed are 46 tables basic on common loading conditions for floor joists, ceiling joists and girders. Where are they substituting SPF? If it is for the studs in the walls, no problem. Simplified maximum stretch tables for selected image and mechanical ranks off Southern Pine lumber in model 2×4 passing 2×12. For each application, a PDF drive are ready. These 46 tables are based upon designing values for perceptibly graded Southern Pine dimension lumber that became effective June 1, 2013. ![]() TABLE 20 RAFTERS 50 PSF LIVE LOAD, 10 PSF DEAD LOAD, 240 DEFLECTION, CD 1.15 (SNOW) TABLE 20 RAFTERS 50 PSF LIVE LOAD, 10 PSF DEAD LOAD, 240 DEFLECTION, CD 1. Tables listing Maximum Spans for Southern Pine joists furthermore rafters are precise below. See Using These Tables and Design Assumptions for additional information. From Professor Gene Wengert, forum technical advisor: Maximum spans given in feet and inches Inside to inside of bearings. The spans in these tables were determined on the same basis as the code-recognized Span Tables for Joists & Rafters and Wood Structural Design Data, both published by the American Wood Council concentrated loads and uplift loads caused by wind were not considered. ![]()
