Course Number: SEM-BD-3006

Length of Course: 3 hours – Several topics can be combined to provide up to an 8 hour seminar session

Seminar Location: This seminar is available for on-site training

In Design Fundamentals of Heavy Timber and Sawn Wood Construction, you’ll learn …


  • Why wood is an important building material and how it compares to steel
  • The National Design Specification for Wood Construction (NDS)
  • Basic theory of structural design (bending, compression, and combined members)
  • The design of mechanical connections used in heavy timber or sawn wood


The basis for this seminar is the use and explanation of the 2005 National Design Specification for Wood Construction (NDS). The NDS has been adopted by all model building codes in the United States—it is currently in compliance with the 2006 International Building Code (IBC) and the 2006 International Residential Code (IRC)—and is used for the design of wood structures worldwide.

In this interactive seminar, we will apply NDS guidelines to specific examples and sample problems of wood construction in order to determine the adjustment factors for specified design values as they relate to conditions of use (temperature, load duration, moisture), member geometry, and member stability. The ultimate goal of this seminar is to provide civil or structural engineers with general design knowledge of the wood elements typically employed in residential and mixed-use construction.

Take away and learning objectives

This course teaches the following specific knowledge and skills:

  • How wood structural elements differ from steel or concrete under standard loading conditions
  • Advantages of using wood structural elements as opposed to steel or reinforced concrete
  • Types of wood typically used in construction and the member properties of those wood types (e.g., allowable stress, modulus of elasticity, orientation of the grain, direction of loading)
  • How to interpret and understand grade markings and the grading process
  • Design of bending members subject to flexural loads (i.e. solid, simple wood beam) using allowable stress design (ASD) and load and resistance factor design (LRFD) methods
  • Design of compression members subject to axial loads (i.e. solid, simple wood column) using allowable stress design (ASD) and load and resistance factor design (LRFD) methods
  • Design of beam or column subjected to combined flexural and axial loading (end loads, side loads, and eccentric loads)
  • Design of nail or spike connections, screw connections, lag bolt connections, and through bolt connections utilizing steel side or gusset plates
