Wood structures are on the rise! Heightened public awareness regarding carbon footprints has dramatically increased the demand for sustainable construction and has initiated a resurgence in the use of wood in tall residential and non-residential buildings. Together with the development of new engineered wood products and advanced connectors, research focus is increasingly set upon wood-based hybrid structures that combine wood with other materials such as concrete. Developing reliable design guidance for wood-based hybrid structures, an important step towards their successful implementation, poses critical research questions related to the structure's performance. The long-term goal of my research program is to systematically address these questions and help lead the development of design guidance for wood-based hybrid structures through experimental, numerical and analytical investigations. My initial NSERC DG was successful in developing a probabilistic design method for wood joints; it was critical for attracting students, leveraging significant additional research funding, and establishing my research group. Over the last five years, I have increasingly shifted my focus from the component level to the structural building level. Addressing research questions related to wood-based hybrid structures holistically will differentiate my research program from other efforts, which tend to focus on individual subsets of these problems. During the next five years, my team will provide solutions to advance two immediately relevant research areas: i) Wood-concrete-composite floors; and ii) Wood-concrete structural load-resisting frames. To explore the construction of tall residential and non-residential wood-concrete hybrid buildings, my research program will encompass the complete chain of design steps, specifically considering constructability in addition to structural behaviour. Conceptual, experimental, numerical, and analytical work will be combined, starting at the element level, continuing to the connections between them and the component level, and subsequently transferring the acquired knowledge to the structural system level. The program will exploit the current momentum of initiatives focused on sustainability and innovative wood construction, leverage successful initiatives in my group, and shape future research agendas in hybrid wood construction provincially, nationally and globally. Ultimately, by taking leadership in this area, successful implementation of the program will have a decisive impact on the structural use of wood and will increase its market share in a variety of residential and non-residential buildings.

木结构建筑正在崛起！公众对碳足迹意识的提高极大地增加了对可持续建筑的需求，并引发了高层住宅和非住宅建筑中木材使用的复苏。随着新型工程木制品和先进连接器的开发，研究重点越来越多地集中在将木材与混凝土等其他材料结合起来的木质混合结构上。 为木质混合结构开发可靠的设计指南是成功实施的重要一步，提出了与结构性能相关的关键研究问题。 我的研究计划的长期目标是系统地解决这些问题，并通过实验、数值和分析研究帮助领导木质混合结构设计指南的开发。 我最初的 NSERC DG 成功开发了木节点的概率设计方法；这对于吸引学生、利用大量额外的研究资金以及建立我的研究小组至关重要。在过去的五年中，我越来越多地将注意力从组件级别转移到结构构建级别。全面解决与木质混合结构相关的研究问题将使我的研究计划与其他工作区分开来，其他工作往往侧重于这些问题的各个子集。 在接下来的五年中，我的团队将提供解决方案来推进两个直接相关的研究领域： i) 木质-混凝土-复合地板；和 ii) 木-混凝土结构抗荷框架。 为了探索高层住宅和非住宅木-混凝土混合建筑的建造，我的研究计划将涵盖完整的设计步骤链，除了结构行为之外，还特别考虑可施工性。概念、实验、数值和分析工作将被结合起来，从元素层面开始，继续到它们和组件层面之间的联系，随后将获得的知识转移到结构系统层面。 该计划将利用当前以可持续发展和创新木结构为重点的举措的势头，利用我小组的成功举措，并制定省级、国家级和全球混合木结构的未来研究议程。最终，通过在这一领域发挥领导作用，该计划的成功实施将对木材的结构使用产生决定性影响，并将增加其在各种住宅和非住宅建筑中的市场份额。
