Course Description

266-Repair Techniques for Wood Trusses, Part 2: Moderate Truss Repairs

Metal plated wood trusses are engineered products that are manufactured in a controlled environment and are now used extensively in the wood frame construction industry. Wood trusses provide the architect or building designer greater flexibility in the design of the structure than conventional framed (stick-built) construction. The design is not as limiting with regard to bearing wall locations which enables longer spans and greater ability to shape complicated roof and ceiling profiles. These pre-manufactured wood trusses facilitate a quicker construction schedule and an overall lower cost.

Wood, a renewable resource, has a great deal of manufacturing flexibility. Wood members are easily formed into standard framing sizes, cut into appropriate lengths with odd angles if necessary, and attached to form the wood structure. However, wood is more susceptible than steel or concrete to damage due to internal defects, handling issues, and long term deterioration. Design or manufacturing errors, shipping damage, miscommunication, and change orders are possible causes for the inadequacy of a wood truss for a specific application and therefore a repair or modification of the pre-manufactured wood truss is required. The purpose of this document is to address various repair techniques that could be used to correct damage to the wood members or metal plates, reinforce trusses that do not meet the required specified design loads, or adjust the truss profile or member location to meet other design requirements.

This course is the second part in a three part series which consists of a total of 11 chapters between all three parts. Chapters 1 through 3 provide an introduction to the terms, concepts, and process involved in truss repairs. Chapters 4 through 11 contain actual truss repairs to provide instruction through the use of example. These chapters are broken down as follows:

Part 1: Introduction and Simple Repair Concepts — Five Chapters:

Chapter 1 — Definitions

Chapter 2 — Repair Design Concepts

Chapter 3 — Wood Truss Repair Connections

Chapter 4 — Member Damage and Defects

Chapter 5 — Plate Damage

Part 2: Moderate Truss Repairs - Four Chapters:

Chapter 6 — Manufacturing Errors

Chapter 7 — Stubs and Extensions

Chapter 8 — Minor Modifications

Chapter 9 — Major Modifications

Part 3: Complex Truss Repairs - Two Chapters — Current Part:

Chapter 10 — Volume Ceiling Changes

Chapter 11 — Girders and Truss Loading.

It is highly recommended to complete Parts 1 and 2 before attempting Part 3. The techniques developed in the earlier chapters provide a good basis for the complex truss repairs presented in Part 3.

As an undergraduate I learned basic truss design concepts in statics and wood design, but I don't recall spending much, if any, time on repair techniques. This course was a nice expansion of my general knowledge of wood trusses given that my work only occasionally involves them.

Great Course; Contractors should be required to take this course so they see the complexity of having to repair a truss when they think they can cut members out with no second thought of the problems they introduced.

18. What is the maximum recommended offset distance when 2x8 (38 x 114 mm) scabs are used? This question needs to have a figure or example number provided. There is not enough information to solve it.

I thought this was an excellent course, I learned a lot about complex repairs even though I am somewhat familiar with wood trusses and basic repair, and the diagrams and illustrations are very good.
