4 Mass timber structural framing systems have high strength-to-weight ratios, are dimensionally stable, and are quickly becoming systems of choice for sustainably minded designers. This presentation will provide a detailed look at the structural design processes associated with a variety of mass timber products, including glued-laminated timber (glulam), cross-laminated timber (CLT), and nail-laminated timber (NLT). Applications for the use of these products in gravity force-resisting systems under modern building codes will be discussed. Other technical topics will include use of mass timber panels as two-way spanning slabs, connection options and design considerations, and detailing and construction best practices.
5 At the end of the this course, participants will be able to: Discuss mass timber products and building systems and their possibilities as structural framing. Compare structural properties and performance characteristics of mass timber products and review their unique design considerations. Review structural design steps for members and connections in common mass timber framing systems. Highlight structural detailing best practices to address items such as shrinkage and expansion, load path continuity, and speed of construction.
