Tall Wood and Hybrid Structures Engineering

木结构建筑正在兴起！提高公众对碳足迹的认识大大增加了对可持续建筑的需求；随着新型工程木制品和先进连接器技术的发展，这已经开始在高层住宅和非住宅建筑中重新使用木材。此外，在加拿大国家建筑规范中采用基于目标的设计方法，如果可以证明等效的性能，则支持高层木结构。在过去的五年中，主席创造和传播了知识，以提高对木材的理解和增加结构使用，并确定了需要进一步可靠和可操作的设计指导的具体应用。在与学术界同事、设计和建筑行业的积极合作中，加拿大研究主席将开展有关高层建筑结构应用的新型连接、组件和系统的研究。主席的主要目标是制定高层木结构的设计指南，这对其工业接受度至关重要。主席小组将处理五个直接相关的研究课题：i)气球框架交叉层压木结构的基于容量的设计程序；ii)防止气球框架高层木结构建筑物不成比例倒塌的机制；木-混凝土复合地板的标准化设计规定；木材混合横向系统的连接细节和整体结构性能；5)胶粘接在木结构工程中的牢固应用。从整体上解决这些研究问题将使该计划与全球其他努力区分开来，这些努力往往侧重于这些问题的单个子集。拟议的项目将利用和推动目前关注可持续性和创新木材建筑的倡议势头，并塑造未来的研究议程。

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.
