NSF Proposal 0122069Engineered Wood Frame Wall Panel System Integrating Prefabricated Truss TechnologyPI: Robert N. EmersonAbstractAn engineered wood frame wall panel system will be investigated that integrates prefabricated metal plate connected truss technology with conventional wood frame wall construction. The wall panel system will appear and handle like conventional walls and be readily adaptable to current construction techniques and applications. However, the engineered wall panel system will be more affordable, durable, safer, and have less environmental impact than conventional site built wood frame construction.Conventional wood frame walls are designed by prescriptive guidelines. They are typically constructed of dimension lumber framework connected together with nails and then sheathed with structural panels (plywood & oriented strand board), insulation panels, or finishing panels (drywall). An engineered wood frame wall panel system will be developed using conventional materials but the dimension lumber framework will be connected with toothed metal plate connectors instead of nails. These moment resistant connections will transform the framework into moment resistant frames that will increase resistance to lateral loads. In addition to the increased structural performance the innovative wall system will gain the benefits of engineered and prefabricated construction.The prefabricated metal plate connected truss industry employs computer-aided design to rapidly engineer custom roof and floor trusses for residential and light-commercial construction. These trusses are then constructed at a factory, shipped to the job site and erected into place. The whole process lends itself to improved efficiency, worker safety, and environmental friendliness. Current prefabricated metal plate connected truss technology will be integrated into a wall panel system that will originally use conventional building materials but will be readily adaptable to new materials. The design and behavior of the engineered wall panel system will be investigated for the proposed research. The technical research will consist of the following phases.1. Integrating the toothed metal plate connector design process into moment resistant frame design.2. Behavior and comparison testing between conventional framework and moment resistant framework. 3. Developing design methodology for combining the lateral resistance provided by moment resistant frames with that provided by the conventional sheathing effect.

NSF提案0122069木制框架墙板系统整合了预制的桁架技术：Robert N. Emersonabstractan工程木制框架墙板系统将进行研究，该系统将整合预制的金属板连接的桁架技术与常规木框壁构造。 墙板系统将像传统的墙壁一样出现和处理，并且很容易适应当前的施工技术和应用。 但是，与传统的木制框架建设相比，工程化的墙板系统将更实惠，耐用，更安全，环境影响更少。规定的木框墙壁是由规定的指南设计的。它们通常由尺寸木材框架与指甲连接在一起，然后用结构面板（胶合板和面向链板），隔热面板或装饰面板（干墙）搭配。 工程木架框架墙板系统将使用常规材料开发，但尺寸木材框架将与齿状金属板连接器而不是指甲连接。 这些抗矩连接将将框架转化为抗矩的框架，从而增加对侧向载荷的阻力。 除结构性能的提高外，创新的墙系统还将获得工程和预制结构的好处。预制的金属板连接的桁架行业还采用计算机辅助设计来快速设计定制的屋顶和地板桁架，以实现住宅和轻商业建筑。 然后在工厂建造这些桁架，运到工作现场并竖立到位。 整个过程都可以提高效率，工人安全和环境友善。当前的预制金属板连接的桁架技术将集成到最初使用常规建筑材料的墙板系统中，但很容易适应新材料。 将对拟议的研究进行研究，研究工程墙板系统的设计和行为。 技术研究将包括以下阶段1。将齿状金属板连接器设计过程集成到抗矩框架设计中2。传统框架与抗矩框架之间的行为和比较测试。 3。开发设计方法，用于将抗瞬间框架与常规护套效应提供的横向电阻结合在一起。
