Equipment Grant for Renovation and Upgrading of the Earthquake Simulator Capability

该奖项为翻新和提高加州大学伯克利分校里士满站地震模拟器(振动台)设施能力的设备赠款提供资金。该模拟器建造于1972年，是美国最大的此类设施之一，自建造以来几乎一直在使用，用于伯克利分校和美国其他大学的教职员工以及咨询公司、工业公司和政府机构的工程师进行的研究。它仍然是全职使用的，但它一再出现故障，显然迫切需要翻新。鉴于这一需要，加利福尼亚州最近拨款23万美元，用于翻新这一设施和相关设施，这项提议要求国家科学基金会提供补充资金，以将振动台设施恢复到目前最先进的能力。具体而言，请拨资金以提供新的和改进的振动台控制系统、新的数据采集设施、模拟器设施的数据采集设施与伯克利校区计算机网络之间的微波链路以及一项可行性研究，以探讨在试验台上增加一个运动部件的可能性，以便能够在三维地震震动条件下进行试验。伯克利的地震模拟器是美国的主要研究资源，依赖于对结构组件和完整系统进行振动试验，以提高对结构地震行为的了解。将这一设施保持在最先进的运营水平是极其重要的。强烈推荐获奖。

This award provides funds for an equipment grant to renovate and improve the capabilities of the earthquake simulator (shaking table) facilities at the Richmond Station University of California, Berkeley. The simulator was constructed in 1972, it is one of the largest such facilities in the United States and has been in use virtually continuously since its construction for research performed by faculty members at Berkeley and other Universities throughout the U.S. and by engineers from consulting companies, industrial corporations and government agencies. It continues to be used on a full-time basis, but it suffers repeated break-downs and is clearly in serious need of renovation. In recognition of this need the State of California has recently allocated $230,000 for renovation of this and related facilities, and this proposal requests complementary funding from the National Science Foundation to restore the shaking table facility to a current state-of-the-art capability. Specifically funds are requested to provide a new and improved control system for the shaking table, new data acquisition facilities, a micro-wave link between the data acquisition facilities at the simulator facility and the computer network on the Berkeley campus and a feasibility study to explore the possibility of adding an additional component of motion to the table so that tests can he performed under three-dimensional earthquake shaking conditions. The earthquake simulator at Berkeley is a major research resource in the U.S. and is depended on to conduct shaking tests of structural assemblages and complete systems required to advance the knowledge of earthquake behavior of structures. It is extremely important to maintain this facility at a state-of-the-art level of operation. An award is strongly recommended.
