About the Presenter:
Jieying Wang, PhD., Senior Scientist, Building Systems Department – FPInnovations
Jieying Wang is a Senior Scientist in the Structural, Durability, and Sustainability Group of the Advanced Building Systems Department at FPInnovations in Vancouver BC. Since she joined FPInnovations (then operating as “Forintek Canada Corp.”) ten years ago, her research has focused primarily on wood durability, moisture performance, and thermal performance of wood-based building envelopes. She worked with building science professionals in developing durable wall assemblies for cross-laminated timber (CLT) construction to facilitate its use in North America. She has been heavily involved in projects on differential movement in mid-rise wood construction and the application of non-load-bearing wood walls in concrete structures. In recent years she has also focused on thermal and durability performance of the building envelope with increasing levels of thermal insulation. She led the projects in developing two design guides for energy efficient building enclosures of MURBs and high-performance houses. She played an important role in developing the Technical Guide for the Design and Construction of Tall Wood Buildings in Canada, and more recently the Mid-rise Wood-Frame Construction Handbook. Jieying has also been extensively involved in developing durability-related building codes and standards in China and Korea for the export market of Canadian wood products. Jieying obtained her PhD in Wood Science from Beijing Forestry University in China in 2000 and worked at the University of Toronto as a post-doctoral research fellow from 2002 to 2005.
About the topic:
The growing interest in wood-frame construction as well as the growth in the urban population prompted the regulatory authorities of many provinces to allow taller buildings in areas that were traditionally low-rise construction.
FPInnovations’ Mid-Rise Wood Frame Construction Handbook consists of ten multi-disciplinary chapters, which have been prepared to facilitate the design and construction of mid-rise wood-frame construction (5- and 6-storey). The handbook captures in a single document the skills of many experts and specialists, and provides practical solutions by making use of the most recently developed technical and research information to assist designers, architects, and engineers.
The presentation will highlight the required design considerations for vertical differential movement in mid-rise wood frame construction. Field measurement of vertical movement as well as wood moisture content changes is used to validate and improve predictions in design. Detailing at critical interfaces is emphasized to reduce differential movement and mitigate its potential impact.
