I agreee with Charles Greenlaw's September 7, 1998 discussion on the subject matter. The 1996 edition of Load and Resistance Factor Design, (LRFD), Manual for Engineered Wood Construction, American Forest & Paper Association, American Wood Council, 1111 19th Street, NW, Suite 800, Washington, DC 20036, Section 7.5.4, Resistance to lateral forces, Section 188.8.131.52, Adjusted lateral resistance, page 32, "End Grain: The reference lateral resistance shall be multiplied by the end grain factor, Ceg = 0.67, for lag screws inserted into the end grain of wood." I believe that LRFD as well as Allowable Stress Design for the design of wood construction will be in the 2000 International Building Code. However, I have heard rumors that there are those who are advocating only LRFD for the design of wood construction in the 2000 International Building Code. Contact Shirin Ader, IBC Secretariat for Structural Chapter 16 through 25, ader(--nospam--at)icbo.org, and express your opinion concerning the possibility of only LRFD (not also ASD) being in the 2000 IBC. If you like LRFD for the design of structural steel, you will love LRFD for the design of wood. Frank E. McClure FEMCCLURE(--nospam--at)aol.com September 8, 1998
