项目摘要

The rapid growth of Canadians urban population and the associated environmental concerns are partlyinfluencing city planners and construction stakeholders to consider "Sustainable Urbanization" alternatives.The sustainable urbanization has emerged as a viable solution towards smart and liveable cities that areresilient and environmentally friendly. In 2015, the National Building Code of Canada has raised the heightlimits on timber frame construction from 4 to 6 storeys. As of 2017, the tallest tall-wood building, is an18-story Brock Commons student residency at the University of British Columbia (UBC). The primary lateralload resisting element, for wind and earthquake loads, is two concrete shear walls. This type of system isknown as hybrid building. Even though light timber frame construction is limited to 6-storey, with theintroduction of mass-timber buildings, coupled with innovative bracing system, in this proposal, it isenvisioned to extend the height to 30-story timber building and develop relevant design guideline. The bracingentails use of dampers and energy-dissipator connectors. It is envisioned that the design guideline wouldenhance the confidence of architects, structural engineers, owners and contractors, towards tall mass-timberbuildings. In the long term the final outcome of the proposed research would increase the volume of wood inbuildings, which will support the forestry business in Canada and engineers at Nordic in particular by:-maximizing the appropriate use of wood in public and private projects,-Strengthening Canada's capacity to produce high quality wood-based products and building systems, and-accelerating adoption of existing and emerging wood-based products and building systems.

加拿大城市人口的迅速增长以及相关的环境问题是部分促进城市规划师和建筑利益相关者，以考虑“可持续的城市化”替代方案。可持续的城市化已成为对智慧和宜居城市的可行解决方案，这些城市的智慧和宜居城市的属性和环境友好。 2015年，《加拿大国家建筑法典》将木材框架建设的高度限制从4层提高到6层。截至2017年，最高的木材建筑是不列颠哥伦比亚大学（UBC）的AN18层的Brock Commons学生居住。对于风和地震载荷，主要的后期抗抗元素是两个混凝土剪力壁。这种类型的系统称为混合建筑。即使轻型木材框架的建设仅限于6层，但在此提案中，大规模木制建筑物的引入以及创新的支撑系统的介绍，但在此提案中，它仍将高度扩展到30层的木材建筑并制定相关的设计指南。用力使用阻尼器和能量分离器连接器的使用。可以预见的是，设计指南将使建筑师，结构工程师，所有者和承包商的信心对高大的大型建筑物的信心。从长远来看，拟议的研究的最终结果将增加木材货币的数量，这将支持加拿大的林业业务，尤其是北欧的林业业务，尤其是： - 最大程度地利用木材在公共和私人项目中，加拿大加拿大加拿大加拿大的能力，可以生产高质量的木材基于木材的产品和建筑系统，以及对现有木材和木材基于木材和建筑系统和建筑系统和建筑系统的采用。
