REG: Equipment Upgrade of MTS 810 Universal Testing Machine

9310491迈耶哥伦比亚大学土木工程和工程力学系将购买MTS490型控制系统，以及一个兼容的软件系统和一台小型DeskPro个人计算机，以升级MTS810型万能试验机。计划进行一系列实验研究，以调查冻融循环、碱-硅酸反应、盐水侵蚀和其他环境影响造成的混凝土材料和结构组件的耐久性，这些因素是导致我国基础设施系统恶化的原因之一。此外，该实验室是我们的基础设施研究中心的中央实验研究设施。预计它将在测试材料和结构部件方面发挥重要作用，各种不同的研究项目将由附属于拟建中心的七所大学组成的联合体确定。

9310491 Meyer The Department of civil Engineering and Engineering Mechanics at Columbia University will purchase and MTS Model 490 control system, together with a compatible software system and a Compact Deskpro Personal Computer, to upgrade an MTS 810 universal testing machine. A series of experimental studies is planned to investigate the durability of concrete materials and structural components damaged by freeze-thaw cycles, alkali-silica reaction, salt-water attack, and other environmental effects, which are among the causes for the deterioration of our nation's infrastructure systems. In addition, the Laboratory is the central experimental research facility of our Center for Infrastructure Studies. It is expected to play a major role in testing materials and structural components within a variety of different research projects to be defined by the consortium of seven universities affiliated with the proposed Center.
