Why would I care? Why would I think anyone else would care. It is in no way related to the Texas State Building Code which is now the 2003 IRC. I know it shouldn't matter who misleads who on these forums but it gets under my skin.įor instance, the Texas Insurance Code is from the 80's and contains voluntary standards for those who wish to buy insurance on the Texas coast. When someone gets an idea he can't support and twists other information to support it, I find it irritating. I got on your case only because you were so adamant about the UBC and other codes. Of course, I don't have the latest revisions and the ICC might add them although it is unlikely since they didn't for the 30 years they were CABO. However, as I originally pointed out, my copies of the UBC, SBC, CABO, IBC and IRC do not require collar ties. revisions to the IRC doesn't include collar ties but who knows, they might get included. So, I was wrong and you were right - until July the Massachusetts code requires collar ties 48” o.c. It will now become law in July which I should have known. The Massachusetts Building Code was revised to add collar ties 20 years after it was first written but only to be deleted by the new IRC which, after a year postponement, was supposed to become law Jan 1st. Neither SFPA, nor its members, have knowledge of the quality of materials, workmanship or construction methods used on any construction project and, accordingly, do not warrant the technical data, design, or performance of the lumber in completed structures.Well done Riversong you’ve done some good research, even better than mine. The conditions under which lumber is used in construction may vary widely, as does the quality of workmanship. The design values contained herein are based on the Southern Pine Inspection Bureau’s Standard Grading Rules for Southern Pine Lumber (2002 edition with supplements) and modified as required by AWC’s National Design Specification® (NDS®) for Wood Construction (2012 edition).Īccordingly, SFPA does not warrant that the design values on which the span tables for Southern Pine lumber contained herein are based are correct, and specifically disclaims any liability for injury or damage resulting from the use of such span tables. SFPA does not grade or test lumber, and accordingly, does not assign design values to Southern Pine lumber. The maximum spans provided herein were determined on the same basis as those in the code-recognized Span Tables for Joists and Rafters(2012 edition) and Wood Structural Design Data (1986 with 1992 revisions), both published by the American Wood Council (AWC). The primary purpose of this publication is to provide a convenient reference for joist and rafter spans for specific grades of Southern Pine lumber.
