Although the benefits of using timber in mid- and high-rise construction are undisputed, there are perceived**shortcomings with respect to the 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.**Mass timber and timber hybrid construction is gaining popularity in modern building construction and**engineering best practices are trying to keep up. While there are many new engineered connectors making their**way to market, some traditional carpentry joints are still cost-effective solutions. One of the more common**connections is a secondary timber beam to a primary timber beam or ledger that is "housed" into the primary**member to create a bearing seat for direct load transfer either through a square mortise or a rounded dovetail.**Such joints have many centuries of performance in buildings, but lack a reliable, modern design basis**congruent with the level of safety and reliability expected of current design standards and building codes.**The company-specific problem that will be addressed is the provision of design guidance for such square or**rounded housing joints, establishing a direct link between the material properties and member dimensions and**the connection performance in terms of strength and stiffness. At the project conclusion, the company will have**a better understanding of how to efficiently and safely design these types of traditional carpentry-type joints.

虽然在中高层建筑中使用木材的好处是无可争议的，但在相应的缺乏适当的设计指导方面存在明显的缺点。克服这些 ** 已知的缺点将使木材及其木材产品衍生物进一步扩展到 ** 非住宅建筑部门。大规模木材和木材混合建筑在现代建筑施工中越来越受欢迎，** 工程最佳实践正在努力跟上。虽然有许多新的工程连接器进入市场，但一些传统的木工接头仍然是具有成本效益的解决方案。一种比较常见的连接方式是将次木梁连接到主木梁或主横梁上，主木梁或主横梁被“容纳”到主构件中，以创建一个轴承座，用于通过方形榫眼或圆形燕尾榫直接传递载荷。这种接头在建筑物中具有许多世纪的性能，但缺乏与当前设计标准和建筑规范所期望的安全性和可靠性水平相一致的可靠的现代设计基础。将解决的公司特定问题是为此类方形或 ** 圆形外壳接头提供设计指导，在材料特性和构件尺寸以及 ** 强度和刚度方面的连接性能之间建立直接联系。在项目结束时，该公司将更好地了解如何有效和安全地设计这些类型的传统木工型接头。
