项目摘要

Over the past two decades there has been a growing interest among the construction stakeholders towards the use of timber as a primary structural material in low- and mid, and high-rise buildings. In this regard, Canada is a global leader in education, research, application, and manufacturing of structural timber. In 2016, the Canadian standard for engineering design in wood included new provisions for the design of Cross Laminated Timber (CLT) structural systems (CSA O86-14). In general, CLT is relatively new material in the market and while advances have been made for the design of floors and wall assemblies using CLT, the development of practical solutions for CLT shear walls lags. The guidelines in CSA O86-14 for designing connection systems in CLT shear walls are difficult to understand and implement in daily design practices. Therefore, in this research proposal, it is aimed to investigate the lateral behavior of CLT shear wall systems (CLT panels together with their connections) to develop a practical guide that supplements the capacity-based design provisions of CSA O86-14. Once developed, designers and builders will be able to easily choose CLT shear walls and connection systems from the practical guide. In this way, prescribed CLT shear wall systems can become a cost-effective solution for buildings of all types of materials.

在过去的二十年中，建筑利益相关者对使用木材作为低层、中层和高层建筑的主要结构材料越来越感兴趣。在这方面，加拿大在结构木材的教育、研究、应用和制造方面处于全球领先地位。 2016 年，加拿大木材工程设计标准纳入了交叉层压木材 (CLT) 结构系统设计的新规定 (CSA O86-14)。一般来说，CLT 是市场上相对较新的材料，虽然使用 CLT 的地板和墙壁组件的设计已经取得了进步，但 CLT 剪力墙的实用解决方案的开发却滞后。 CSA O86-14 中有关 CLT 剪力墙连接系统设计的指南在日常设计实践中很难理解和实施。因此，在本研究提案中，旨在研究 CLT 剪力墙系统（CLT 板及其连接件）的横向性能，以制定实用指南，补充 CSA O86-14 基于容量的设计规定。一旦开发完成，设计师和建筑商将能够从实用指南中轻松选择 CLT 剪力墙和连接系统。通过这种方式，规定的 CLT 剪力墙系统可以成为所有类型材料建筑的经济高效的解决方案。
