Continuous-moment connection for CLT floor panels

迫切需要研究开发木材的新颖和增值应用，以最大限度地从可持续采伐加拿大丰富的森林中获益，并通过扩大可持续材料木材的使用来减少建筑物的碳足迹。与轻型框架木结构或混凝土结构相比，交叉叠层木材(CLT)具有许多优点，如高水平的预制和快速安装。因此，CLT构成了许多结构应用的有前景的解决方案，包括用作大型住宅和商业建筑的地板。然而，由于目前缺乏针对单层板间节点的具体设计指南，导致采用窄柱网架和次梁体系的结构方案不经济且效率低下。利用实验和数值方法，该联盟项目将研究硬木钥匙作为CLT地板高性能接头的可行性。该项目将促进为CLT地板系统中的此类节点制定设计指南，这将构成许多应用的有前途的解决方案。

There is an acute need for research to develop novel and value-added applications for wood to maximize the benefits from sustainably harvesting Canada's abundant forests and to reduce the carbon footprint of buildings by expanding the use of the sustainable material wood. Cross-laminated timber (CLT) provides many benefits when compared to either light-frame wood or concrete construction, such as a high-level of prefabrication and fast erection. As such, CLT constitutes a promising solution for numerous structural applications, including as floors for large residential and commercial buildings. However, the current lack of specific design guidance for the joints between individual CLT floor panels leads to uneconomical and inefficient structural solutions with narrow column grids and secondary beam systems. Using experimental and numerical methods, this Alliance project will investigate the viability of hardwood keys as high-performance joints for CLT floor panels. The project will facilitate the development of design guidance for such joints in CLT floor systems that constitute a promising solution for many applications.
