NIST, originally founded as the National Bureau of Standards in 1901, works to strengthen U.S. industry's competitiveness; advance science and engineering; and improve public health, safety, and the environment. One of the agency's basic functions is to develop, maintain, and retain custody of the national standards of measurement, and provide the means and methods for comparing standards used in science, engineering, manufacturing, commerce, industry, and education with the standards adopted or recognized by the Federal Government. As an agency of the U.S. Commerce Department's Technology Administration, NIST conducts basic and applied research in the physical sciences and engineering and performs related services. The Institute does generic and precompetitive work on new and advanced technologies. NIST's research facilities are located at Gaithersburg, MD 20899, and at Boulder, CO 80303. Major technical operating units and their principal activities are listed below. For more information contact the Public Inquiries Desk, 301-975-3058.

This volume. Earthquake Protection in Buildings Through Base Isolation, describes energy dissipation systems and reviews their applications and effectiveness. These documents provide guidelines for evaluating energy dissipating systems and a directory of the systems used in buildings and other structures. The original reports in Japanese were published by the Building Center of Japan under the sponsorship of the Japanese Ministry of Construction (MOC). The MOC provided these reports to the National Institute of Standards and Technology for their translation into English and for publication. The subjects addressed in these reports include: the history and types of passive energy dissipators; their applications, evaluations, and performance; and case histories of these devices exposed to seismic loading. KEYWORDS: active damper, base isolation; damping; devices; evaluation, passive damper; performance, seismic; structures; wind loads. Translated from Japanese by Amerind Publishing Co. Pvt.

Volume 1, Earthquake Protection in Buildings through Base Isolation, describes energy dissipating devices, reviews their use for application, and discusses their effectiveness. Volume 2, Survey Report on Framing of the Guidelines for Technological Development of Base isolation Systems Buildings, addresses the performance of these devices and provides examples of buildings installed with such devices and case studies. The two-volume reports were produced by the Building Center of Japan under sponsorship of the Japanese Ministry of Construction (MOC) to describe the state-of-the-art of energy dissipating devices and to review their use in mitigating damages from earthquakes. These reports were made available to the National Institute of Standards and Technology (NIST) for translation into English and for publication through the Panel on Wind and Seismic Effects. The Panel is one of 16 comprising the U.S.-Japan Program in Natural Resources (UJNR). The Panel, composed of U.S. and Japanese agencies participating with representatives of private sector organizations, develops and exchanges technologies aimed at reducing damages from high winds, earthquakes, storm surge, and tsunamis. NIST provides the chairman and secretariat of the U.S.-side Panel on Wind and Seismic Effects; the Public Works Research Institute, MOC, provides the Japan-side chairman and secretariat. These volumes were translated under contract by the National Technical Information Service (NTIS). The English translations convey the technical contents of the two reports; no further efforts were made to editorialize the translated manuscripts. The U.S.-side Panel is indebted to the Japanese-side Panel for sharing useful design and construction information about an emerging technology for mitigating damages to buildings and other structures from earthquakes and high winds. The U.S.-side also is appreciative of the efforts of Mr. Tatsuo Murota, Director, Structural Engineering Department of the Building Research Institute (BRI), MOC, and his BRI
