Engineering Essentials: Timber Connection Design Workshops

This October, we are pleased bring back Dr. Ghasan Doudak to present two full-day workshops on timber connection design so that you can choose the date/location that works best for you. The following topics will be addressed at the workshops:

  • Mechanics of wood
  • Heavy timber connections
  • Modern timber connections
  • Ductility in connections

You won’t want to miss the next installment of our ‘Engineering Essentials’ workshop series. For engineers designing in wood, or interested in expanding their capacity to do so, this is an extremely valuable learning opportunity.

Timber bridges have a long history of construction and use throughout North America, including Ontario, for roadways, railways and logging roads. The Canadian Highway Bridge Design Code (CHBDC), together with the Canadian Wood Council publication Wood Highway Bridges from 1992 are typically referenced by designers of timber bridges in Ontario. This new reference is intended to provide updated background information for designers as they embark on proposing and designing timber highway bridges for primary and secondary roads. The reference is divided into three parts:

Part 1 – Wood Bridges – Design and Use
Part 2 – Opportunities & Current Limitations
Part 3 – Design Examples

Part 1 provides background information on topics including wood materials, bridge systems, prefabrication, durability and species availability. Details of costs, construction cycle and sustainability are also provided. Part 1 concludes with examples of a variety of completed highway bridges from North America and Europe.

Part 2 of this reference is intended to provide designers and authorities with highlights of the current edition of the CHBDC on subjects related to the wood highway bridges, including areas that will require future development in the code. Additional references to other resources for advancing practitioner knowledge of and advancing the state of the art in wood bridge design are provided.

Part 3 has two fully worked design examples of a two-lane 18-m span wood highway bridge designed in accordance with the latest provisions of the CHBDC and the best available information from current literature. Each example is based on a single-span, simply-supported glued-laminated girder bridge. One bridge has a glued-laminated deck and the other has a stress-laminated deck. These examples are intended to help designers understand the key issues as they undertake wood highway bridge design. Durability through detailing and choice
of materials is discussed.
