Wood structures are on the rise! Heightened public awareness regarding carbon footprints has dramatically increased the demand for sustainable construction; together with the development of novel engineered wood products and advanced connector technology, this has initiated a resurgence in the use of wood in tall residential and non-residential buildings. Further, the adoption of the objective-based design approach in the National Building Code of Canada that favors tall wood construction if equivalent performance can be demonstrated. Over the past 5 years, the Chair created and disseminated knowledge for heightened understanding and increased structural use of wood, and identified specific applications for which further reliable and actionable design guidance is needed. In active collaboration with academic colleagues and the design and construction industries, the Canada Research Chair will conduct research regarding novel connections, components and systems for structural applications in tall buildings.The main objective of the Chair is to develop of design guidance for tall wood structures, which is vital to their industrial acceptance. The Chair's team will address five immediately relevant research topics: i) Capacity-based design procedures for balloon-framed cross-laminated timber structures; ii) Mechanisms to prevent disproportionate collapse of balloon-framed tall-wood buildings;iii) Standardized design provisions for wood-concrete-composite floors;iv) Connection detailing and overall structural behaviour of wood-hybrid lateral systems; and v) Robust applications of adhesive bonding in wood structural engineering.Addressing these research questions holistically will differentiate the program from other efforts globally, which tend to focus on individual subsets of these problems. The proposed program will exploit and fuel the current momentum of initiatives focused on sustainability and innovative wood construction and shape future research agendas.

木结构正在上升！公众对碳足迹的认识提高了对可持续建筑的需求大大增加了。随着新型工程木材产品和高级连接器技术的开发，这在高大的住宅和非住宅建筑中启动了木材的复兴。此外，如果可以证明同等的性能，则在加拿大国家建筑法典中采用了基于目标的设计方法，该方法有利于高大的木材结构。在过去的5年中，主席创建并传播了知识，以提高理解和增加木材的结构使用，并确定了需要进一步可靠且可行的设计指导的特定应用。在与学术同事和设计与建筑行业的积极合作中，加拿大研究主席将进行有关高大建筑中结构应用的新颖连接，组件和系统的研究。 ，这对于他们的工业接受至关重要。主席的团队将介绍五个立即相关的研究主题：i）基于气球框架跨层压木结构的基于能力的设计程序； ii）防止气球框架高的木材建筑物比例过度崩溃的机制； iii）针对木质混凝土复合材料地板的标准化设计规定； iv）连接细节和木质杂交横向系统的整体结构行为； v）粘合键合在木材结构工程中的强大应用。对这些研究问题进行补充，将整体上的计划与全球其他努力区分开来，这些计划倾向于集中在这些问题的各个子集上。拟议的计划将利用和助长目前的倡议势头，这些倡议的重点是可持续性和创新的木材建设，并塑造了未来的研究议程。
