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集成预制桁架技术的工程木框架墙板系统PI：Robert N.将研究一种工程木框架墙板系统，该系统将预制金属板连接桁架技术与传统木框架墙结构相结合。 墙板系统将像传统的墙壁一样出现和处理，并且容易适应当前的建筑技术和应用。 然而，工程墙板系统将更实惠，耐用，更安全，并且比传统的现场建造的木框架结构对环境的影响更小。传统的木框架墙是根据规定的指导方针设计的。它们通常由用钉子连接在一起的规格木材框架构成，然后用结构板（胶合板定向刨花板）、绝缘板或饰面板（干墙）覆盖。 一个工程木框架墙板系统将使用传统材料开发，但尺寸木材框架将与带齿金属板连接器连接，而不是钉子。 这些抗力矩连接将把框架转换成抗力矩框架，这将增加对横向载荷的抵抗力。 除了提高结构性能外，创新的墙体系统还将获得工程和预制建筑的好处。预制金属板连接桁架行业采用计算机辅助设计，为住宅和轻型商业建筑快速设计定制屋顶和地板桁架。 这些桁架然后在工厂建造，运到工地并竖立到位。 整个过程有助于提高效率，工人安全和环境友好。目前的预制金属板连接桁架技术将被集成到墙板系统中，该墙板系统最初将使用传统的建筑材料，但将易于适应新材料。 工程墙板系统的设计和行为将被调查的拟议研究。 技术研究将包括以下阶段。1.将齿形金属板连接器设计过程整合到抗弯框架设计中.常规框架与抗弯框架的性能及对比试验。3.开发设计方法，将抗弯框架提供的侧向阻力与传统的蒙皮效应提供的侧向阻力相结合。
