REG: Equipment Upgrade of MTS 810 Universal Testing Machine

9310491 Meyer哥伦比亚大学土木工程与工程力学系将购买MTS Model 490控制系统，以及兼容的软件系统和Compact Deskpro个人电脑，以升级MTS 810通用试验机。我们计划进行一系列的实验研究，以调查混凝土材料和结构部件在冻融循环、碱-硅反应、盐水侵蚀和其他环境影响下的耐久性，这些影响是导致我国基础设施系统恶化的原因之一。此外，该实验室是我们基础设施研究中心的中心实验研究设施。预计它将在各种不同的研究项目中发挥主要作用，这些项目将由隶属于拟议中心的七所大学组成的财团确定。

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.
