Development of Performance Based Structural Response Modification Factors (R-Factors)

结构响应修正系数（R系数）与实际 结构在显著屈服水平下的地震反应 弹性响应，由计算的响应谱表示， 强力运动唱片 因此，R因子提供了一个基本的 通过这种机制，强运动数据可以应用于 抗震设计的许多建筑类型。 本研究的目标 项目的目的是评估一般的R因子概念， 通过分析当前可用的R因子值， 强震记录和建筑物反应数据，并开发 抗震设计中R系数的分配和使用指南 常用的结构体系。 改进和完善 R-因子方法和R-因子的发展， 建筑类型将大大有利于工程界， 全国建筑业。

Structural response modification factors (R-Factor) relate the actual earthquake response of structures at significant yield level to the elastic response as represented by the response spectrum computed from strong-motion records. As a result, R-Factors provide a basic mechanism through which strong-motion data can be applied in the seismic design of many building types. The objectives of this research project are to assess the R-Factor concept in general, to evaluate currently available R-Factor values through the analyses of strong-motion records and building response data, and to develop guidelines for assigning and utilizing R-Factors in the seismic design of commonly used structural systems. The improvement and refinement of the R-Factor approach and the development of R-Factors for specific building types will significantly benefit the engineering community and the construction industry nationwide.
