Chapter 5 - Design of Wood Framing The principal method of design for wood-framed construction has historically been allowable stress design (ASD). This chapter uses the most current version of the ASD method (AF&PA, 1997), although the load resistance factored design method (LRFD) is now available as an alternative (AF&PA, 1996a).
view moreDuring the wood processing (see Section 5), several modification methods are available to increase wood stability and durability. • Impregnation: Lumina and cavities in the cell walls are filled with bulking chemicals (e.g. monomers, polymers, resins, and waxes). These bulking chemicals hardly react with the wood .
