Fire Safety Challenges of Tall Wood Buildings

Acknowledging the growing importance of designing sustainable buildings and addressing overpopulation concerns, the development of engineered wood products has introduced the possibility of constructing high-rise timber structures that can improve both these conditions. However, as a combustible material, one of the biggest barriers to construction of tall timber buildings is the potential fire risk resulting from the combustible structure. In November 2012, the Fire Protection Research Foundation commissioned the Fire Safety Challenges of Tall Wood Buildings study to address this concern. Phase I of this two-phase study seeks to collect the available knowledge of fire safety in timber structures and identify gaps in knowledge that would further the understanding of fire performance of tall timber buildings. Results of the study, including a summary of timber construction and fire dynamics, is presented herein.

Shear Testing of Cross-Laminated Beams

This testing program was carried out by the Advanced Building Systems (ABS) Department of FPInnovations in response to a request made by Mrs. Julie Frappier of Nordic Engineered Wood and Mr. Étienne Lalonde of Canadian Wood Council (CWC) for the evaluation of the shear stress resistance of one hundred fifty two (152) cross-laminated timber (CLT) beams. All specimens were manufactured by Nordic Engineered Wood and delivered to FPInnovations’ testing facilities in Québec City. The main objective of this study was to evaluate the in-plane shear stress of CLT depending of its orientation and the number of plies. Specific Gravity and Moisture Content measurements were also determined for each specimen.

IBS5 – Thermal Performance of Light-Frame Assemblies

“A man’s home is his castle” is an old familiar phrase, but if truth be told, the castles of old were cold and draughty. Today’s homes are now havens of comfort with efficient central heating systems and well insulated building envelopes. We count on the walls and roofs of our houses to keep the heat in during the winter months and the heat out during the sweltering days of summer. Today’s home buyers demand energy efficient houses with high insulation values. “Lowering energy use” has become the goal as the cost and environmental implications of energy use are considered. Insulation levels are now being required by many code authorities. Stricter thermal requirements mean that designers must understand the impact of the materials and assemblies used on thermal performance. Because of its long history of use, wood-frame construction has well established insulating properties and record of performance. The effect of other construction systems on insulation properties is not widely known or understood. This publication will examine current knowledge of the thermal performance of wood and other framing techniques. This information will assist designers and builders to select construction techniques that provide the best thermal performance.

IBS3 – Fire Resistance and Sound Transmission

Fire is an ever-present danger for building occupants. Research and experience confirm that fire safety in a house or apartment has little to do with the combustibility of the structural materials used in its construction. In fact, the occupants’ safety is far more dependent on their own awareness of fire hazards (open flames, etc.), the contents of their home (furniture, etc.), and the fire protection measures designed into the building. Minimization of sound transmission in single- and multi-family residential buildings is also an important factor to ensure occupant comfort, and is closely related to fire-resistant construction. The intent of this brochure is to demonstrate how wood frame buildings meet code requirements by providing examples of wood-based light frame building systems designed to maximize fire safety and minimize sound transmission.

Monotonic Quasi-Static Testing of CLT Connections

This testing program was carried out by the Advanced Building Systems (ABS) Department of FPInnovations in response to a request from Mrs. Julie Frappier from Nordic Engineered Wood for the evaluation of the mechanical properties of three (3) different assemblies for attaching Cross Laminated Timber (CLT) panels. Each of the assemblies consisted of six (6) specimens for a total of eighteen (18) tests. All specimens were manufactured by Nordic Engineered Wood and delivered to FPInnovations’ laboratory in Québec City.

The key objective was to evaluate the mechanical properties pertinent for the design of CLT panel connections exposed to in-plane loading such as diaphragms or shear walls. The evaluation of the ultimate loading capacity (𝐏𝐮𝐥𝐭) and the stiffness (K) of the connections are thus the main focus of this study.
