Engineering Research Equipment Grant: Renovation and Up- grading of the Earthquake Simulator Capability

这是一笔设备拨款，用于升级和提高加州大学伯克利分校地震工程研究中心地震模拟器（振动台）设施的能力。20英尺× 20英尺的振动台于1972年完工并开始运行，至今仍是美国最大的振动台之一。自建成以来，这个设施几乎一直在使用，供伯克利大学和美国乃至世界其他大学的教职员工、咨询公司的工程师、为工业、企业和政府机构提供服务。虽然震动台继续使用，但到1985年，该设施明显需要进行翻新。1986年，加利福尼亚州和国家科学基金会拨出资金翻新这一设施，并探索将运动中缺失的第三个跨国组成部分加入其中的可能性。这些拨款所拟进行的翻修和改善工程，大部分已完成。加州大学伯克利分校认识到在地震地面运动可能具有的三个跨国分量中实现台架同步能力的重要性，已为设计拨出额外的资金。建设和安装必要的改造，以增加现有的电力。这一行动将支助将目前的液压油能力必要地提高到目前的两倍左右。第三个跨国组成部分的加入将允许对三维测试结构对多向激励的反应进行综合分析和实验研究。​该项目将把我国地震工程实验研究能力提升到一个更高潜力成果的新水平。

This is an equipment grant to upgrade and improve the capability of the earthquake simulator (shaking table) facility at the Earthquake Engineering Research Center of the University of California at Berkeley. The 20 ft. x 20 ft. shaking table that was completed, and began its operation, in 1972 is still one of the largest in the United States. This facility has been in use virtually continuously since its construction for research performed by faculty members at Berkeley and at other universities throughout the U.S. and the world, by engineers from consulting firms, and for services to industry, corporations and government agencies. Although the shaking table continues to be used, by 1985 it became evident that the facility was in serious need of renovation. In 1986 the State of California and the National Science Foundation allocated funds for the renovation of this facility as well as to explore the possibility of adding the missing third transnational component of motion to the table. Most of the renovation and improvement work contemplated in these allocations has been completed. In recognition of the importance of implementing simultaneous capability for the table in the three transnational components that a seismic ground motion can have, the University of California at Berkeley has allocated additional funds for the design, construction and installation of the modifications necessary to increase the existing electrical power. This action will provide support for the necessary upgrading of the present hydraulic fluid capacity to about twice the current capacity. The addition of the third transnational component will permit conducting integrated analytical and experimental research on the response of three-dimensional test structures to multi- directional excitations. This project will elevate the nation's earthquake engineering experimental research capability to a new level of higher potential achievements.
