Engineering Research Equipment Grant: Sevo-Controlled Electro-Hydraulic Acutators for Structural Testing

实验性地震工程研究允许第一手观察建筑和建筑组件在模拟地震荷载下的行为。这笔研究设备赠款将提供两个110 kip的伺服控制电液执行器，以满足科罗拉多大学结构工程实验室目前和即将进行的研究需求，该实验室目前正在进行几个由国家科学基金会资助的关于配筋砖石结构构件抗震抗力机制的实验研究项目。特别是，将测试全尺寸楼层高度的配筋砌块墙板。此外，在几个新的研究项目中将需要这些致动器，这些项目涉及评估填充钢筋混凝土框架的非弹性抗震性能，以及验证正在实验室开发的用于抗震性能测试的计算机控制的拟动力试验设备。新的致动器不仅将扩大当前研究活动的范围，还将为未来的地震工程研究打开新的机遇。

Experimental earthquake engineering research allows first-hand observation of behavior of building and building components to simulated earthquake loadings. This research equipment grant will provide two 110-kip servo-controlled electro-hydraulic actuators to meet the current and pending research needs in the structural engineering laboratory of the University of Colorado, which is currently engaged in several NSF-supported research projects on the experimental investigation of the seismic load- resistance mechanisms of reinforced-masonry structural components. In particular, tests of full-scale story-height reinforced-masonry wall panels will be tested. Furthermore, the actuators will be needed in several new research projects that involve the evaluation of the inelastic seismic performance of masonry-in-filled reinforced-concrete frames, as well as the verification of a computer-controlled pseudodynamic test facility that is being developed in the laboratory for seismic performance testing. The new actuators will not only enlarge the scope of the current research activities, but will also open new opportunities for future earthquake engineering research.
