Base isolation systems represent an attractive strategy for protecting structures from the effects of earthquakes. Several different systems exist and the subject has world-wide interest. Successful application of base isolation can reduce structural costs while providing protection against the effects of earthquakes. An important part of the design of structures is the proper specification of the design response spectrum. The research project will develop realistic design spectra for base-isolated buildings and will address low frequency response. The results of the research will provide the designer with design response spectra which will be appropriate for base-isolated structures.

基础隔离系统代表了一种有吸引力的保护结构免受地震影响的策略。存在着几种不同的系统，这一主题引起了全世界的兴趣。基础隔离的成功应用可以降低结构成本，同时提供对地震影响的保护。结构设计的一个重要部分是设计反应谱的合理规定。该研究项目将为基础隔离建筑开发现实的设计频谱，并将解决低频响应问题。研究结果将为设计人员提供适用于基础隔震结构的设计响应谱。
