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，建筑利益相关者对将木材用作低层和高层建筑的主要结构材料的兴趣越来越大。在这方面，加拿大是结构木材的教育，研究，应用和制造业的全球领导者。 2016年，木材工程设计标准包括跨层压木材（CLT）结构系统设计的新规定（CSA O86-14）。通常，CLT是市场上相对较新的材料，尽管使用CLT设计了地板和墙壁组件的设计，但开发了用于CLT剪切壁的实用解决方案。 CSA O86-14的指南在日常设计实践中很难理解和实施CLT剪力墙中设计连接系统的指南。因此，在这项研究建议中，旨在研究CLT剪切壁系统（CLT面板及其连接）的横向行为，以开发一个实用指南，以补充CSA O86-14的基于容量的设计规定。一旦开发，设计师和建筑商将能够轻松从实用指南中选择CLT剪力墙和连接系统。这样，规定的CLT剪力壁系统可以成为所有类型材料建筑物的成本效益解决方案。
