This Small Business Innovation Research Phase I project surrounds the development of a sacrificial energy dissipation mechanism for structural applications with globally significant commercial potential. The structures that are the intended initial application for the device represent over $2 billion in annual shipments per year in the United States alone. However, these structures exist all over the globe. This device will open up the market for these structures in regions of high seismicity, where structures of other material composition currently corner the market. Implementation of this device will also create significant cost savings in comparison to competing structures, as the speed of construction is much more rapid, reducing overall construction costs, especially in low-income regions of the world that experience seismic activity. The asymmetric axial response concept is unique in the field of structural engineering and this research offers a novel addition to the existing body of knowledge.The intellectual merit of this project centers on a unique concept that will allow certain types of structures, currently not permitted due to governing safety codes, to be built in high-seismic regions. The concept is that of asymmetric axial strength and stiffness, whereby a mechanical device loaded axially in one direction provides a different response to that of the device loaded axially in the opposite direction. Although this project's objective is to develop this concept for a specific application, there exists the potential for this concept to be developed for additional applications in the future. Ongoing university research, funded by industry, seeks to find a solution to this specific seismic design problem, but has not taken the direction that this project intends to take. The ultimate research objective for this Phase I effort is to determine a geometric configuration such that the concept can be physically realized in the form of a working mechanical device. The research will include finite element modeling and numerical simulations coupled with the testing of physical prototype specimens through cyclic axial loading sequences. It is anticipated that a working configuration will be discovered, tested, modeled, and placed into a full-frame model for additional simulation.

这个小型企业创新研究阶段I项目围绕着具有全球巨大商业潜力的结构应用的牺牲能量耗散机制的发展。该设备的初始申请的结构仅在美国就代表了每年超过20亿美元的年度货物。但是，这些结构都存在于全球。该设备将在高地震性地区开放这些结构的市场，目前其他材料组成的结构目前在市场上旋转。与竞争结构相比，该设备的实施还将创造大量的成本节省，因为施工速度要快得多，可以降低整体建筑成本，尤其是在世界低收入地区经历地震活动的情况下。不对称的轴向响应概念在结构工程领域是独一无二的，这项研究为现有知识体系提供了新颖的补充。该项目的智力优点集中在一个独特的概念上，该概念将允许某些类型的结构，目前由于管理安全代码而允许的安全代码允许，该结构允许在高分区域内构建。 这个概念是不对称的轴向强度和刚度，即机械装置沿轴向沿一个方向升压的机械设备对沿相反方向轴加的设备的响应提供了不同的响应。尽管该项目的目标是为特定应用程序开发此概念，但仍有可能将来为其他应用开发此概念。正在进行的大学研究由行业资助，试图找到解决这个特定地震设计问题的解决方案，但并未采取该项目打算采取的方向。 I阶段I努力的最终研究目标是确定几何配置，以便可以以工作机械设备的形式物理地实现该概念。该研究将包括有限元建模和数值模拟，并通过循环轴向加载序列测试物理原型样品。预计将发现，测试，建模并将其放置为全帧模型以进行其他仿真。
