日本东北大地震之隔减震建筑考察与思考

作者于2011年6月14日-18日参加了中日建筑结构技术交流会组织的中日专家联合考察团,实地考察了仙台地区在3月11日日本东北地区太平洋近海地震中的地震灾害情况,重点对隔、减震建筑在此次里氏8.8级大地震中的表现进行了调研。该文概述了隔、减震技术及其在日本应用的基本情况,重点介绍了隔减震结构在此次地震中的表现,并给出了隔减震结构应用的若干结论和体会。

INVESTIGATION AND CONSIDERATION OF SEISMIC ISOLATION AND ENERGY DISSIPATION STRUCTURES IN TOHOKU EARTHQUAKE

As one member of the Chinese and Japanese expert investigatory group,the author had attended the earthquake hazard investigation activities which were organized by China-Japan Technique Committee on Building Structures during June 14th to 18th,2011.An on-the-spot investigation had been carried out on earthquake calamities brought by the Pacific coast of Tohoku Earthquake on March 11th in Sendai and emphatically the performance of seismic isolation and energy dissipation structures in this magnitude 8.8 earthquake.This paper summarizes seismic isolation and energy dissipation techniques and the basic situation of their application in Japan.The performance of the structures which used these techniques in this earthquake is emphatically introduced.Some conclusions and experience on the application of seismic isolation and energy dissipation structures are also given.
