Uni-Directional Shaking Table (UDST) system controller for the Applied Laboratory for Advanced Materials and Structures (ALAMS)

购买单向振动台（UDST） MTS系统控制器将允许在地震载荷下确定各种结构部件和由新材料制成的系统的地震性能和损伤状态。新型材料的使用将大大提高各种结构在地震荷载事件下的使用寿命，并将对实现基础设施及其管理的可持续解决方案产生深远影响。然而，通过振动台试验来了解其损伤状态是至关重要的。本研究计划的具体工程追求涉及以下内容：******自定心结构和装置：本研究的重点是开发低成本，易于建造的具有自定心能力和地震时高能量耗散能力的结构元件，组件和系统。安装了这种创新装置或结构元件的建筑物在地震事件中几乎不会受到损坏。***新一代木结构：这项研究有助于加拿大木材工业朝着高层木结构建筑的方向发展，其中大型木制品（交叉层压木材，胶合木）的振动台测试将有助于开发基于性能的木结构设计。货架结构：在北美，商业仓库的数量正在显著增加（例如，Costco，亚马逊商店），其中存储货架结构在内部竖立，用于存储货物和/或展示商品。本课题的重点是机架式楼盖结构的抗震设计。2014年加拿大引入了抗震设计规定（CSA S16-2014），在这一领域进行了有限的研究。因此，本研究项目的主要目标是为新机架结构和缺陷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导方针。振动台试验对于验证改进的抗震设计程序和设计准则的充分性是必不可少的。******使用拟议的MTS控制器将大大提高UBCO先进材料和结构应用实验室（ALAMS）的测试能力。ALAMS已经获得了250 kN疲劳额定MTS执行器和振动台的顶部和底座。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，以确定损伤状态，并为创新结构制定抗震设计指南。所要求的设备将进一步帮助培养多样化的学生群体，他们将通过使用具有更好的抗震性能和更长的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对环境无害。

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.
