1996 EDITIONLRFDLOAD AND RESISTANCE FACTOR DESIGNMANUAL FOR ENGINEEREDWOOD CONSTRUCTIONCopyright © 1996American Forest & Paper Association
FOREWORDThis manual represents the beginning of a new era inthe design of wood structures. It is the first wood designmanual in the U.S. presented in the modern Load andResistance Factor Design (LRFD) format. It is also thefirst design manual to provide guidance for selection ofmost wood-based structural products used in the constructionof wood buildings.The complete wood LRFD package includes thismanual and its design supplements and guidelines. Themanual contains the consensus-based AF&PA/ASCE 16-95 standard, its commentary and examples ofits use. Design supplements and guidelines are organizedalong product lines and contain design information forspecific products and details of design specific to thoseproducts.The modular format of the complete package is essentialfor a design package that covers such a broad rangeof products. This format provides the ability to quicklylocate specific design information in one of the wellmarkeddesign supplement or guideline documents.PREFACEThe American Forest & Paper Association (AF&PA)has developed this manual for design professionals.AF&PA and its predecessor organizations have providedengineering design information to users of structural woodproducts for over 50 years, first in the form of the WoodStructural Design Data series and then in the NationalDesign Specification ® (NDS ® ) for Wood Construction.This manual represents the culmination of 10 yearsof development of LRFD procedures for wood products,which in turn is built on 20 years of research on this topic.The basis of this Manual can be directly traced to a prestandardactivity of the American Society of CivilEngineers (ASCE), a wood-industry sponsored LRFDspecification development project and the consensus adoptionof the specification through a joint AF&PA/ASCEcommittee. Without the dedication of the many technicalexperts who contributed to these projects and the broadsupport of virtually the entire North American forest productsindustry, this Manual could not have become a reality.Every effort has been made to ensure that the dataand information in the Manual are as accurate and completeas possible. AF&PA does not, however, assume anyresponsibility for errors or omissions in the Manual norfor engineering designs or plans prepared from it.This Manual was written by David S. Gromala, P.E.,under contract to AF&PA, with the guidance and assistanceof AF&PA staff and numerous industry technicalexperts who participated on the AF&PA LRFD committee.AF&PA/ASCE 16-95 NOTATION AND GLOSSARYAF&PA/ASCE 16-95, Standard for Load and ResistanceFactor Design (LRFD) for Engineered WoodConstruction, is contained in its entirety in the final sectionof this Manual. For the convenience of the designengineer, the notation and glossary sections of AF&PA/ASCE 16-95 are duplicated in this section.AMERICAN WOOD COUNCIL
