It can be observed from this review that most fire safety provisions are similar in nature, whether the Chinese, Canadian or American provisions are applied. However, the Chinese code seems to be slightly more restrictive than the North American building codes with respect to wood-use allowances.
The key objective of this study was to evaluate the surface burning characteristics (flame spread rating) of glued-laminated timber (glulam) decking in accordance with CAN/ULC S102 test method . This is part of a test series aimed at evaluating the flame spread rating of mass timber components, such as cross-laminated timber (CLT) and structural composite lumber (SCL).
More specifically, this study is solely focused on mass timber assemblies that are thick enough to be treated theoretically as semi-infinite solids (thermally thick solids) as opposed to thermally-thin, which is typical of traditional combustible finish products. The tested specimen in this series meets the provisions related to “heavy timber construction”, per paragraph 184.108.40.206 of Division B of the National Building Code of Canada.
In this study, FPInnovations observed and documented the use of a geogrid and woven geotextile as a culvert foundation improvement method on a resource road built in Ontario. Following the installation, annual culvert elevation surveys and culvert end angle measurements have been conducted by FPInnovations as a means in which to evaluate the effectiveness of the foundation improvement method. Following three years of re-measurements, the use of the geogrid and woven geotextile have not shown to improve the culvert foundations at this site. FPInnovations will continue to monitor the site and will use the knowledge gained to provide recommendations for culvert foundation improvement designs.
