Ductile glued moment-resisting timber connections

尽管在中高层建筑中使用木材的好处是毋庸置疑的，但人们意识到 不足之处在于相应缺乏适当的设计指导。克服这些感知到的 缺陷将允许木材及其木制品衍生品进一步扩展到非住宅领域 建筑业。用粘合钢棒连接木材有一系列的优点，例如，形成 连接非常坚固，同时仍有利于钢屈服所需的延性破坏模式。AS 这样，它们构成了许多结构应用的有前途的解决方案，包括抗力矩。 连接作为结构抗震系统的一部分。然而，在加拿大，粘合的木材 弯矩连接尚未得到广泛应用，部分原因是人们意识到木质易裂的风险 失败，部分原因是缺乏设计指导。 在本工程中，将对粘钢节点的抗弯性能进行试验研究。 不同的几何配置(钢筋数量和有/无劈裂钢筋)和不同 外部加载配置(单调加载和循环加载)。在统计上意义重大的样本数量 将进行测试，并将监测选定测试子集中的载荷-变形行为。这项研究 结果将允许行业合作伙伴安全地设计木结构的抗弯连接，使用 粘合的接头。这项研究将进一步为后续的合作研究奠定基础，解决 更广泛的设计参数和应用。该项目有可能对 木材的结构使用，增加其在非住宅建筑中的市场份额，从而产生积极影响 通过使用更多的可再生资源来实现建筑业的可持续性。

Although the benefits of using timber in mid- and high-rise construction are undisputed, there are perceived shortcomings with respect to a corresponding lack of appropriate design guidance. Overcoming these perceived shortcomings will allow timber, and its wood product derivatives, to further expand into the non-residential construction sector. Timber connections with glued-in steel rods have a series of advantages, e.g., the formation of very stiff and strong connections while still facilitating a desired ductile failure mode of steel yielding. As such they constitute a promising solution for numerous structural applications, including for moment-resisting connections as part of the seismic force resisting system of a structure. In Canada, however, glued timber moment connections are not yet widely used, partially due to the perceived risk of a brittle wood splitting failure and partially due to a lack of design guidance. In this project, moment-resisting connections with glued-in steel rods will be experimentally tested considering different geometric configurations (number of steel rods and with/without splitting reinforcement) and different external loading configurations (monotonic and cyclic loading). A statistically significant number of specimens will be tested, and the load-deformation behaviour in a selected subset of tests will be monitored. The research results will allow the industry partner to safely design moment-resisting connections for timber structures using glued joints. The research will further lay the groundwork for subsequent collaborative research addressing a wider range of design parameters and applications. The project has the potential to have an impact on the structural use of timber, increase its market share in non-residential construction, and thus positively influence sustainability of the construction industry by using more renewable resources.
