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.

购买单向振动台 (UDST) MTS 系统控制器将能够确定由新型材料制成的各种结构部件和系统在地震载荷下的抗震性能和损坏状态。新型材料的使用将大大提高地震荷载事件下各种结构的使用寿命，并对基础设施及其管理的可持续解决方案产生深远影响。然而，通过进行振动台测试来了解它们的损坏状态至关重要。本研究提案感兴趣的具体工程追求涉及以下内容：******自定心结构和装置：本研究重点开发低成本、易于构建的具有自定心结构的元件、组件和系统。 -地震时的定心能力和高耗能能力。配备此类创新设备或结构元件的结构在地震事件中几乎不会受到损坏。***新一代木结构：这项研究帮助加拿大木材工业迈向高层木结构建筑计划，其中对大型木制品进行振动台测试（跨木结构）层压木材、胶合木）将有助于开发基于性能的木结构设计。***货架结构：整个北美商业仓库的数量正在显着增加（例如好市多、亚马逊商店），其中在内部建立了存储货架结构来存储货物和/或展示商品。该项目重点关注机架覆盖建筑的抗震设计。加拿大于 2014 年引入抗震设计规定 (CSA S16-2014)，在此领域进行的研究有限。因此，该研究项目的主要目标是为新的机架结构和有缺陷的机架结构的抗震加固/改造提供创新的抗震设计解决方案和指南。振动台测试对于验证改进的抗震设计程序和设计指南的充分性至关重要。******使用拟议的 MTS 控制器将大大提高先进材料和结构应用实验室 (ALAMS) 的测试能力）在UBCO。 ALAMS 已经固定了 250 kN 疲劳额定 MTS 执行器以及振动台顶部和底座。所要求的 MTS 控制器将使振动台发挥作用，并帮助研究人员进行振动台测试，以确定损坏状态并为创新结构制定抗震设计指南。所需的设备将进一步帮助培训多元化的学生群体，他们将通过使用具有更好抗震性能和较长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，这在经济上可行且对环境无害。
