Evaluation of Seismic Base Isolation Systems

基础隔震系统为减轻地震荷载对结构的影响提供了一种很有吸引力的方法。通过将结构与地震地面运动部分分离，可以减少结构内部的惯性力，从而显著降低结构损坏的可能性。作为一种设计策略，基础隔震概念正在世界各地受到相当大的关注。这项研究项目将制定指导方针，帮助实践工程师决定基础隔震系统策略是否适合特定结构。该项目将制定一份全面的最先进的总结，确定各种基础隔震系统的动态响应特性，并制定基础隔震系统的使用指南。然后，这些信息将被系统地编目，供工程师使用。

Base isolation systems offer an attractive method to mitigate the effects of earthquake loadings on structures. By partially decoupling the structure from the earthquake ground motion, the inertial forces within the structure can be reduced, thus significantly decreasing the potential for damage to the structure. The base isolation concept is receiving considerable attention throughout the world as a design strategy. This research project will develop guidelines that will help the practicing engineer to decide whether the base isolation system strategy is appropriate for a particular structure. The project will develop a comprehensive state-of-the-art summary, determine the dynamic response characteristics of various base isolation systems, and develop guidelines for the use of base isolation systems. This information will then be systematically catalogued for use by engineers.
