Prescribed CLT shear wall systems using capacity-based design for multi-story buildings

在过去的二十年里，建筑业的利益相关方对在低、中、高层建筑中使用木材作为主要结构材料的兴趣越来越大。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，加拿大的木材工程设计标准包括了交叉叠层木材(CLT)结构系统设计的新规定(CSA O86-14)。总的来说，CLT在市场上是一种相对较新的材料，虽然使用CLT设计地板和墙体组件已经取得了进展，但CLT剪力墙实用解决方案的开发滞后。CSA O86-14中关于CLT剪力墙连接体系设计的指南很难理解，也很难在日常设计实践中实施。因此，在本研究方案中，旨在研究CLT剪力墙体系(CLT板及其连接)的侧力性能，以制定实用指南，以补充CSA O86-14基于能力的设计规定。一旦开发完成，设计者和建筑商将能够很容易地从实用指南中选择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有效的解决方案。

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.
