The purchase of a Uni-Directional Shaking Table (UDST) MTS system controller will allow determining the seismic performance and damage states of various structural components and systems made of novel materials under seismic loading. Utilization of novel materials will substantially improve the service life of various structures under seismic load events and will have a profound impact to reach a sustainable solution to infrastructure and its management. However, it is critical to understand their damage states by performing shaking table tests. The specific engineering pursuits of interest to this research proposal relate to the following:******Self-Centering Structures and Devices: This research focuses on the development of low-cost, easy to build structural elements, components and systems with self-centering capability and high energy dissipation capacity during earthquakes. Structures fitted with such innovative devices or structural elements will experience almost no damage during a seismic event.***New Generation Timber Structures: This research helps Canadian wood industries towards tall timber building initiatives where shaking table testing of large timber wood products (cross-laminated timber, glulam) will help develop performance based design of timber structures.***Rack Structures: The number of commercial warehouses are increasing significantly across North America (e.g., Costco, Amazon store) where storage rack structures are erected inside for storing goods and/or displaying merchandise. This project focuses on the seismic design of rack clad buildings. Limited research has been conducted in this area where seismic design provisions in Canada was introduced in 2014 (CSA S16-2014). Hence, the main goal of this research project is to provide innovative seismic design solutions and guidelines for new rack structures and seismic strengthening/retrofitting of deficient rack structures. Shake-table tests are essential to verify the adequacy of the improved seismic design procedure and design guidelines.******The use of the proposed MTS controller will substantially improve the testing capability of the Applied Laboratory for Advanced Materials and Structures (ALAMS) at UBCO. ALAMS has already secured a 250 kN fatigue rated MTS actuator and shaking table top and base. The requested MTS controller will make the shaking table functional and help researchers perform shaking table tests to define damage states and develop seismic design guidelines for innovative structures. The requested equipment will further help train a diversified group of students who will develop a sustainable Canadian infrastructure system through the use of novel materials and structural systems with better seismic performance and long service life, which will be economically viable and environmentally sound.

购买单向振动桌（UDST）MTS系统控制器将允许确定在地震载荷下由新型材料制成的各种结构组件和系统的地震性能和损害状态。新型材料的利用将大大改善地震负荷事件下各种结构的使用寿命，并将产生深远的影响，以实现对基础设施及其管理的可持续解决方案。但是，通过执行摇桌测试来了解其伤害状态至关重要。该研究建议的特定工程追求与以下各项有关：******自我居中的结构和设备：本研究的重点是发展低成本，易于构建结构性元素，组件和具有自我居中能力以及地震期间高能量耗散能力的组件和系统。装有这种创新设备或结构元素的结构在地震事件中几乎不会造成任何损害。***新一代木材结构：这项研究可帮助加拿大木材工业迈向高大的木材建筑计划，在这些木材建筑计划中，摇晃桌子的摇桌测试大型木材木材产品（交叉层压的木材，胶合，胶合物）将帮助开发跨质量的基于木制架构的型号。 Costco，Amazon Store），在其中竖立了存储架结构，用于存储商品和/或展示商品。该项目着重于架子层建筑物的地震设计。在该领域进行了有限的研究，该领域在2014年在加拿大引入了地震设计规定（CSA S16-2014）。因此，该研究项目的主要目标是为新机架结构提供创新的地震设计解决方案和指南，并为不足的机架结构提供地震加强/改造。摇式测试对于验证改进的地震设计程序和设计指南的充分性至关重要。******使用拟议的MTS控制器的使用将显着提高UBCO上高级材料和结构（ALAMS）的应用实验室的测试能力。 阿拉姆（Alams）已经获得了250 kN的疲劳额定速度执行器，并摇晃桌面和底座。请求的MTS控制器将使摇晃的桌子发挥作用，并帮助研究人员执行摇晃的桌子测试，以定义损害状态并制定创新结构的地震设计指南。要求的设备将进一步帮助培训一群多元化的学生，这些学生将通过使用具有更好地震性能和长期使用寿命的新型材料和结构系统来开发可持续的加拿大基础设施系统，这将在经济上可行且在环境上是合理的。
