9500424 French Digital data acquisition and control equipment will be purchased to replace the current system which is based on an early version Micro Vax II computer (vintage 1986). Funds are being used to upgrade the servovalves on the existing hydraulic actuators. Specific projects for which the equipment will be used included: NSF Precast Seismic Structural systems (PRESSS) project regarding the evaluation of ductile precast frame connections; NSF Faculty Award for Women investigation of real-time large scale earthquake simulation tests (effective force test method); NSF Research Initiation Award (RIA) to investigate the nonlinear cyclic behavior of concrete-filled tube beam-columns; Minnesota Department of Transportation (MnDOT) study of the effects of thermal and mechanical cyclic loading on the bond between fiber reinforced plastic (FRP) reinforcement and concrete; MnDOT investigation to characterize the material properties of asphalt mixtures; and the development of an accelerated load test platform for concrete pavement research.

9500424法国将购买数字数据采集和控制设备，以取代目前的系统，该系统以早期版本的Micro Vax II计算机（1986年）为基础。资金用于升级现有液压执行器上的伺服阀。 将使用该设备的具体项目包括：NSF预制抗震结构系统（PRESSS）项目，涉及延性预制框架连接的评估; NSF女性教师奖，用于实时大规模地震模拟测试的调查（有效力试验法）;美国国家科学基金会研究启动奖（RIA）研究钢管混凝土梁柱的非线性循环性能;明尼苏达州交通部（MnDOT）研究了热循环和机械循环荷载对纤维增强塑料（FRP）钢筋和混凝土之间粘结的影响; MnDOT调查以表征沥青混合料的材料性能;以及开发了用于混凝土路面研究的加速荷载试验平台。
