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。 该仪器用于振动台，能够在30，000磅有效载荷（高达50，000磅）上模拟水平和垂直方向的地震运动，行程分别为+10和+5英寸。 UCI地震工程研究的一个独特方面是强调基于风险和可靠性考虑的地震安全工程，以及其在结构地震保护控制工程方面的创新发展。 收购振动台将提高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，该地区容易发生地震，但没有这种规模的大型设施。 这样一个表是必不可少的实验验证新的理论结果，以及创新的控制设备和有效的改造技术的发展。 振动台将使研究人员能够研究结构的倒塌机制，如桥梁和公路系统，生命线，建筑物和二级系统在水平和垂直地震运动的组合下，具有大幅度位移，并调查地震保护系统的有效性，包括主动，被动和混合系统受到水平和垂直地面运动。 振动台还将增强UCI作为太平洋沿岸国家工程师互动/培训中心的潜力。 UCI在测试设备、二次系统和结构内容方面与工业界合作处于非常有利的地位。 ***
