9413859 Haroun, Medhat This is an instrumentation award. The instrumentation is for a shake table capable of simulating earthquake motions on a 30,000 lb payload (up to 50,000 lbs) in both the horizontal and vertical directions with strokes of + 10 and + 5 inches, respectively. A unique aspect of the earthquake engineering research thrust at UCI is its emphasis on seismic safety engineering based on risk and reliability considerations, and its innovative development in control engineering for seismic protection of structures. The acquisition of the shake table would increase UCI's research and teaching capabilities and aid in establishment of a unique large testing facility in Southern California, an area prone to earthquakes yet with no major facility of this size. Such a table is essential for experimental verification of new theoretical results, as well as the development of innovative control devices and of effective retrofit techniques. The shake table will enable researchers to study the collapse mechanisms of structures such as bridges and highway systems, lifelines, buildings, and secondary systems under combined horizontal and vertical earthquake motions with large amplitude displacements and to investigate the effectiveness of seismic protective systems, including active, passive, and hybrid systems subjected to both horizontal and vertical ground motions. The shake table will also enhance UCI's potential as an interactive/training center from engineers from the Pacific rim countries. UCI is in an excellent position to collaborate with industry for testing equipment, secondary systems and structural contents. ***

9413859 Haroun, Medhat 这是一个乐器奖。 该仪器适用于振动台，能够模拟 30,000 磅有效负载（最高 50,000 磅）在水平和垂直方向上的地震运动，行程分别为 + 10 英寸和 + 5 英寸。 UCI 地震工程研究的一个独特方面是它强调基于风险和可靠性考虑的地震安全工程，以及结构抗震控制工程的创新发展。 购买振动台将提高 UCI 的研究和教学能力，并有助于在南加州建立一个独特的大型测试设施，该地区是一个地震多发地区，但没有如此规模的大型设施。 这样的表格对于新理论结果的实验​​验证以及创新控制装置和有效改造技术的开发至关重要。 该振动台将使研究人员能够研究桥梁和公路系统、生命线、建筑物和二级系统等结构在具有大幅位移的水平和垂直地震运动下的倒塌机制，并研究地震防护系统的有效性，包括主动地震防护系统。 、被动和混合系统受到水平和垂直地面运动的影响。 摇床还将增强 UCI 作为太平洋沿岸国家工程师互动/培训中心的潜力。 UCI 在与测试设备、辅助系统和结构内容方面的行业合作方面处于有利地位。 ***
