Third US-Japan Workshop on Seismic Retrofit of Bridges and Fourth US-Japan Workshop on Earthquake Protective Systems for Bridges

该项目于1996年12月在日本筑波召开了一个关于山脊和筑波抗震改造的美日研讨会。本次研讨会将邀请两国的研究人员和设计人员讨论桥梁防震系统的发展和应用以及桥梁抗震改造方面的进展。将涵盖的主题包括：(1)创新的保护系统；(2)基础隔震桥梁设计方法；（三）设计由孤立桥梁承载的设施，以适应移动；(4)性能的全面验证。还将对同一座桥的美国和日本隔离设计进行比较。该计划还包括实地考察几座与基地隔离的桥梁，以及日本目前正在建设的几座主要桥梁。由美国国家科学基金会和联邦公路管理局共同支持的研讨会将进一步强调主动和混合添加，将检查受北岭和阪神- Awaji地震影响的地震隔离桥梁和建筑物的性能。这些研讨会还将确定发展对美日双方都有利的合作项目的机会。

9703522 Buckle This project convenes a US-Japan Workshop on Seismic Retrofit of ridges and Tsukuba, Japan in December 1996. This Workshop will involve researchers and designers from both countries to discuss progress in the development and application of earthquake protective systems to bridges and seismic retrofit of bridges. topics to be covered include: (1) innovative protective systems; (2) design methods for base isolated bridges; (3) design of utilities carried by isolated bridges so as to accommodate movement; and (4) full-scale verification of performance. A comparison of US and Japanese isolation designs for the same bridge will also made. The program also includes site visits to several base-isolated bridges as well as several major bridges currently under construction in Japan. The Workshop which is jointly supported by NSF and Federal Highway Administration, will provide an added emphasis on active and hybrid addition, the performance of seismically isolated bridges and buildings affected by the Northridge and Hanshin- Awaji earthquakes will be examined. Opportunities for the development of cooperative projects beneficial to both the U.S. and Japan will also be identified as a result of these workshops.
