A new control and data acquisition system is required to preserve and upgrade our mechanical testing capabilities in the Laboratoire d'étude de la durée de vie des infrastructures publiques in the Department of Civil and Water engineering. This laboratory serves not only as the base centre of many research projects spanning from the study of cracking behaviour of ultra-high performance fibre reinforced concrete to the investigation of cyclic loading response of large-scale prefabricated aluminum bridge decks, but also as the setting for the design and development of novel methods for testing and evaluating materials. This new control and data acquisition system is urgently required to replace the current 20-year-old system, for which recent repairs have been extremely difficult to implement and replacement parts are no longer available. A breakdown of the present system would jeopardize significant portions of our research activities and would thereby impact the progress of some of our graduate students towards completion of their program. The importance of the actual control and data acquisition system cannot be understated. It is used to control and run several testing apparatuses: one 500 kN universal testing frame with t-slot testing table and a large vertical opening, one 1 MN stocky universal testing frame as well as a set of five (5) hydraulic actuators located in our large-scale environmental room. Including the hydraulic power-pack and the various manifold and valve systems, this controller and data acquisition system is at the top of a 1.5+ M$ worth of equipment used every day in research projects associated to 10 professors. The control and data acquisition system package sought are essentially three (3) components: 1) the Controller; 2) a collection of dedicated powerful interface boards; and 3) the Control Software suite. The MTS FlexTestr100 Controller is a reliable and versatile servocontroller that provides real-time reliable closed-loop control, along with a wide array of possible configurations, making it the perfect controller for our various testing set-ups. The collection of dedicated interface boards includes all the hardware needed with the controller to adequately run the hydraulic systems (frame and actuators) and capture in parallel the signals from a variety of sensors (strain, displacement, pressure, etc.). Finally, the MTS Control Software allows to create the tests and link together all of the aforementioned hardware elements. The key outcome for the users (a) a highly improved control of the test progress (essential in studies involving cracking of localized damage mechanisms); (b) an increased measurement resolution and precision, both during static and cyclic loading schemes (a necessity for some of the newest standardized test methods); and (c) a simplified and significantly upgraded capacity for developing and testing experimental procedures (a key element for optimally exploiting the testing infrastructure).

土木和水利工程系公共基础设施实验室实验室需要新的控制和数据采集系统来保留和升级我们的机械测试能力。该实验室不仅是从超高性能纤维混凝土开裂行为研究到大型预制铝桥面板循环荷载响应研究等众多研究项目的基地中心，也是设计和开发材料测试和评估新方法的场所。迫切需要这种新的控制和数据采集系统来取代当前已有 20 年历史的系统，该系统最近的维修极其困难，并且不再提供替换零件。现行系统的崩溃将危及我们研究活动的很大一部分，从而影响我们一些研究生完成其课程的进度。实际控制和数据采集系统的重要性不可低估。它用于控制和运行多个测试设备：一个带有 T 型槽测试台和大垂直开口的 500 kN 通用测试框架、一个 1 MN 坚固的通用测试框架以及位于我们大型环境室中的一组五 (5) 个液压执行器。该控制器和数据采集系统包括液压动力包以及各种歧管和阀门系统，是 10 名教授每天在研究项目中使用的价值 1.5+ M$ 的设备中的佼佼者。所寻求的控制和数据采集系统包本质上是三 (3) 个组件： 1) 控制器； 2）一系列专用的强大接口板集合； 3) 控制软件套件。 MTS FlexTestr100 控制器是一款可靠且多功能的伺服控制器，可提供实时可靠的闭环控制以及多种可能的配置，使其成为适合我们各种测试设置的完美控制器。专用接口板的集合包括控制器充分运行液压系统（框架和执行器）并并行捕获来自各种传感器（应变、位移、压力等）的信号所需的所有硬件。最后，MTS 控制软件允许创建测试并将所有上述硬件元件链接在一起。用户的主要成果（a）大大改进了对测试进度的控制（对于涉及局部损坏机制破裂的研究至关重要）； (b) 在静态和循环加载方案中提高测量分辨率和精度（某些最新标准化测试方法的必要条件）； (c) 简化并显着升级的开发和测试实验程序的能力（优化利用测试基础设施的关键要素）。
