最新的抗震规范在用于抗震建筑物设计的等效侧向力的定义中包括了反应修正系数。反应修正系数（R）用于降低线弹性设计谱，以考虑结构的耗能能力。本文介绍了对不同地震记录和延性系数的反应修正系数的评价。特别注意的是，在短周期范围内，线弹性反应谱的折减小于中长期结构的值。一个理想化的和简单的变化的响应修正系数作为振动周期的函数，适用于抗震规范制定，也提出。
Most recent seismic codes include response modification factors in the definition of the equivalent lateral forces that are used for the design of earthquake resistant buildings. The response modification factors (R) are used to reduce the linear elastic design spectrum to account for the energy dissipation capacity of the structure. The evaluation of these response modification factors for various sets of earthquake records and ductility factors is presented herein. Special attention is given to the short period range where the reduction of linear elastic response spectra is smaller than the values for intermediate and long period structures. An idealized and simple variation of the response modification factor as a function of the period of vibration, suitable for seismic codes formulation, is also presented.
