Although the benefits of using timber in non-residential construction are undisputed, there are perceived shortcomings with respect to the serviceability of timber floors, specifically, vibration, deflection, acoustic and fire encapsulation. Overcoming these shortcomings will allow timber, and its wood product derivatives, to further expand into the construction sector. Hybrid structures that integrate engineered wood products (EWPs) with other materials, such as concrete, can significantly increase the use of timber in structures beyond current limitations. Timber-concrete-composite (TCC) floors are a successful example of hybrid structural components and are commonly used in Europe. The main consideration when designing TCC floors is the appropriate connector performance as is the governing design factor. In the Engage project, one specific low-cost but high-performance TCC system (combination of nail-laminated timber decks and truss plates as connector) will be tested under different test set-ups (small-scale shear tests to determine the connector performance and full-scale bending tests to determine the floor performance). The research will allow the industry partner to safely design TCC floors and will further lay the groundwork for subsequent collaborative research addressing a wider range of design parameters and a wider range of applications of TCC floors in timber-based hybrid structures. The project has the potential to have an impact on the structural use of timber, increase its market share in a variety of applications, and thus positively influence sustainability of the construction industry by using more renewable resources.

尽管在非住宅建筑中使用木材的好处是毋庸置疑的，但人们意识到 木地板的适用性方面的缺陷，特别是振动、挠度、声学和 火灾封装法。克服这些缺点将使木材及其木制品衍生品能够 进一步向建筑领域扩张。集成工程木制品的混合结构(EWPS) 使用其他材料，如混凝土，可以显著增加目前结构中木材的使用量 限制。木材-混凝土-组合(TCC)楼板是混合结构构件的成功范例 并在欧洲普遍使用。在设计TCC地板时，主要考虑的是适当的 连接器性能是主导设计因素。 在Engage项目中，一个特定的低成本但高性能的TCC系统(钉层压组合 木材甲板和作为连接件的桁架板)将在不同的试验装置下进行试验(小规模剪切试验以 确定连接器性能和全尺寸弯曲测试以确定地板性能)。这个 研究将使行业合作伙伴能够安全地设计TCC地板，并将进一步为 后续的协作研究涉及更广泛的设计参数和更广泛的 TCC楼板在木质混合结构中的应用。该项目有可能对 木材的结构性使用，增加了其在各种应用中的市场份额，从而产生了积极影响 通过使用更多的可再生资源来实现建筑业的可持续性。
