近年来，现行的抗震规范开始考虑采用被动耗能装置的结构设计。对这些装置及其结构进行合理抗震设计的一个重要问题是制定计算其设计地震力的数值方法。根据对近二十年来墨西哥记录的单自由度系统在加速度下的动力响应的研究，制定了估计强度折减系数的表达式，该系数应用于降低5%阻尼的弹性设计强度谱，以建立具有不同塑性和粘性耗散能力组合的结构的设计地震力。
In recent years, current seismic codes started contemplating the design of structures with passive energy dissipating devices. One important issue for the rational seismic design of these devices and the structure that contains them is the formulation of numerical methods to estimate their design seismic forces. From the study of the dynamic response of single-degree-of-freedom systems subjected to accelerograms recorded in Mexico during the last two decades, expressions to estimate the strength reduction factor that should be used to reduce the elastic design strength spectra for 5 percent damping, to establish the design seismic forces for structures having different combinations of plastic and viscous energy dissipating capacities, are formulated.
