Evaluation of Seismic Base Isolation Systems

基础隔震系统提供了一种有吸引力的方法来减轻 地震荷载对结构的影响。 通过部分解耦 结构不受地震地面运动、惯性力 在结构内可以减少，从而大大减少 对结构的潜在损害。 基础隔震的概念是 作为一种设计， 战略 这项研究项目将制定指导方针， 实践工程师决定是否基础隔震系统 策略适合于特定的结构。 该项目将 制定一个全面的最先进的总结，确定动态 各种基础隔震系统的响应特性，并开发 基础隔震系统使用指南。 这些信息 然后将被系统地编目以供工程师使用。

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.
