This webinar was co-sponsored by ASCE's Structural Engineering Institute (SEI) and ASCE Continuing Education
Instructor: Tom Williamson, P.E., F.ASCE
Course Length: 1 Hour
Purpose and Background
Glued laminated timber or glulam has been successfully used in the U.S. for over 75 years in a wide range of commercial buildings and bridges. Many of these structures and bridges remain in service after over 50 years but engineers are generally not familiar with the design and use of glulam. In the past decade a number of innovative glulam structures have been constructed in North America including a 300 foot clear span ice rink at the 2010 Winter Olympics, the new Terminal C at the Raleigh Durham International Airport, the Bullitt Center in Seattle which is the first building in the U.S. to meet the Living Building Challenge criteria and many more.
CLT is just being introduced into North America after over 15 years of use in Europe and other countries where CLT framed buildings exceeding 8 stories are being successfully constructed. A number of 5-6 story CLT buildings are currently planned or have been built in Canada and there is a widespread interest in this technology among U.S. design professionals. CLT will be recognized in the 2015 International Building Code and in the 2015 National Design Specification for Wood Construction and this webinar will introduce design professionals to this exciting new wood engineering technology.
As designers embrace the concept of sustainable design and the use of environmentally friendly products, wood becomes a material of choice. Wood is truly the only sustainable structural material and it a carbon sink and as such its use greatly benefits the environment. It also has excellent life cycle performance characteristics compared to other common structural materials. Together glulam and CLT offers new and unlimited opportunities for using wood in non-residential construction.
But if design professionals are going to explore the use of these technologies they need a basic understanding of the design intricacies associated with these products to ensure that efficient, durable and structurally sound buildings are the end result.
Primary Discussion Topics
- Overview of glulam and CLT as modern engineered wood products to meet any commercial building design challenge
- Review of key design considerations for glulam and CLT of primary importance to a design professional
- Development of allowable design properties for glulam and CLT and their proper application
- Overview of building code provisions for glulam and CLT
- Available industry design standards for glulam and CLT and where to get more advanced design guidance
- Importance of proper designing and detailing of connections to ensure long lasting and structurally sound structures
- Fire safety of glulam and CLT
- Potential for using glulam and CLT in "tall" wood structures of 6 stories and more
