From the Preface
This manual is intended to aid instruction in structural design of wood structures using load and resistance factor design. It contains design examples ranging from simple to complex and covering many design scenarios. Solutions are based on the 1996 LRFD Manual for Engineered Wood Construction, developed
using MathCAD 2000 Professional software by MathSoft, Inc. Some problems have been posed as stand-alone problems, but there are several sets in which all
examples in the set are associated with a single structure. This may prove useful for those instructors who wish to expose students to slightly more
comprehensive problems. Problem sets may be broken into parts and assigned as individual problems.
The 1996 LRFD Manual for Engineered Wood Construction consists of many parts that for clarity in notation are delineated here. Embedded in its entirety
with the LRFD Manual is AF&PA/ASCE 16-95, Standard for LRFD for Engineered Wood Construction. This standard carries with it the confidence of a consensus
document that has undergone review and deliberations by a wide spectrum of engineers within the American Society of Civil Engineers (ASCE) and the
American Forest and Paper Association (AF&PA). The other parts of the LRFD Manual include introductory information, case studies, examples and explanations of basic design provisions. Also included as part of the manual, but under separate cover, is a series of supplements and guidelines for different wood products and connections provided by various wood industry cooperators.
In the solutions where a particular provision of AF&PA/ASCE 16-95, Standard for LRFD for Engineered Wood Construction is cited, reference is made to the
LRFD Standard and the corresponding provision number, e.g. LRFD Standard 1.4.3 The 1996 LRFD Manual includes Supplements for non-proprietary materials and
Guidelines for proprietary materials. These will be referred to as Supplements or Guidelines. For example, the supplement for lumber is called the Lumber
Supplement; the guideline for proprietary connectors is referred to as the Metal Connectors Guideline.
While every effort has been made to provide complete and accurate solutions, no guarantee is made or implied concerning solution accuracy or the suitability of designs proposed in the solutions. This manual is intended to illustrate design procedures for educational purposes and not to propose particular designs or design details. The financial support of the Wood Products Council (American Wood Council of the American Forest and Paper Association, Southern Pine Council (Southern Forest Products Association and the Southeastern Lumber Manufacturers Association) and the Wood Truss Council of America) made the
development of this manual possible and it is gratefully acknowledged.
