Introduction to Structural Design of Wood Buildings per the 2015 NDS  - April 10-12, 2017 - Blacksburg, Virginia
General Information

What You Will Learn

This course will focus on practical code-conforming design of wood structures based on provisions of the 2015 NDS and other AWC standards. At the beginning of the course, we will review the structural design properties of lumber, the derivation of allowable design stresses, and safety factors that are involved in the design process. We will design simple framing elements showing what factors apply to the allowable design properties of lumber and timbers and explain why the various factors apply to a design situation.

In Calculating Wind Loads on Low-Rise Structures per WFCM Engineering Provisions, the engineering provisions of the 2015 WFCM will be used to calculate shear, uplift, and overturning loads for various building components. This presentation will provide background and examples for calculation of these forces which will enable designers and code officials to quickly determine wind design loads for projects.

Permanent truss bracing design will be covered by using the 2015 BCSI Book that contains prescriptive bracing details that can provide valuable input to the registered design professional for a project. The BCSI Book also can be an excellent resource for the building inspectors in their framing inspection work.

The objectives of this course are a mastery of wood design basics and understanding of the many factors routinely used and required by the 2015 National Design Specification for Wood Construction (ANSI/AWC NDS-2015). All design calculations will be based on our strict interpretation of the ANSI/AWC NDS-2015. In addition to presenting designs that are consistent with model code provisions, the instructors will discuss "good practice" when it may apply to the worked examples. Two hours will be devoted to structural testing demonstrations and related discussion at the Brooks Forest Products Research Center.

The course notebook will contain the structural analyses and demonstrated designs presented in the course, thereby relieving the participants of extensive note taking. The registration fee includes lunch, refreshment breaks, and the following publications:

  • ANSI/AWC NDS-2015 National Design Specification (NDS) for Wood Construction with Commentary
  • AWC NDS-2015 Supplement: Design Values for Wood Construction
  • ANSI/AWC SDPWS-2015 Special Design Provisions for Wind and Seismic (SDPWS) with Commentary
  • ANSI/AWC WFCM-2015 Wood Frame Construction Manual with Commentary
  • 2015 Building Component Safety Information (BCSI) Book
