Engineered Wood Construction: Structural Properties for LRFD
Publication: Journal of Structural Engineering
Volume 121, Issue 9
Abstract
This paper addresses the procedures established for the derivation of design properties for use in load and resistance factor design (LRFD) of structural wood products. It covers derivation of reference strength (stress) and reference resistance (force or moment) values using either a format conversion or a reliability-based conversion process. Reference design properties will be used with the first edition of the LRFD Specification for Engineered Wood Construction . The majority of the reference design properties were derived through format conversion. Derivation examples are provided for glued laminated timber, structural panels, dimension lumber, and timber piles. Development of end-use condition adjustment factors is reviewed. Impacts of the transition from allowable stress design to LRFD are discussed.
