Experimental investigation of controlled rocking cross-laminated timber walls

加拿大的人口正在增长，因此需要通过建造更高的建筑来加强城市建设。与此同时，加拿大对气候变化采取行动的承诺需要将建筑活动的碳足迹降至最低。最有希望同时建造更高更绿的建筑的方法之一是使用交叉叠层木材(CLT)，这正在扩大木结构的覆盖范围。在这种背景下，Guardian Structures作为加拿大仅有的CLT生产商之一走在了前列。设计更高建筑的最具挑战性的方面之一涉及到这些结构在严重地震中的安全性。该项目将在麦克马斯特应用动力学实验室进行的大规模实验测试的基础上，研究可控摇摆CLT墙的创新配置。实验结果将被用来更好地理解如何对CLT墙和基础之间的界面进行建模，从而指导设计程序，使高层木结构建筑具有更高的弹性和经济性。

Canada's population is growing, leading to a need to intensify cities by building taller. At the same time,Canada's commitment to action on climate change necessitates minimizing the carbon footprint of buildingactivities. One of the most promising means of building both taller and greener is by using cross-laminatedtimber (CLT), which is expanding the reach of wood structures. Within this context, Guardian Structures isleading the way as one of the only Canadian producers of CLT.One of the most challenging aspects of designing taller buildings relates to the safety of these structures duringa severe earthquake. This project will investigate the innovative configuration of controlled rocking CLT walls,based on large-scale experimental testing to be conducted at McMaster's Applied Dynamics Laboratory. Theexperimental results will be used to better understand how to model the interface between a CLT wall and thefoundation, leading towards design procedures that will enable more resilient and economical tall woodbuildings.
