2000年NEHRP规定中开发、验证了具有阻尼系统的屈服建筑物的等效侧向力和模态分析程序。文件中描述了每一程序的技术基础，以及为列入《规定》而采取的简化措施。本文给出了装有屈服、粘弹性、线性粘性和非线性粘性阻尼装置的建筑物的有效阻尼、有效周期和高阶模态阻尼比的计算方法。
Equivalent lateral force and modal analysis procedures for yielding buildings with damping systems were developed, validated, and incorporated in the 2000 NEHRP Provisions. The technical basis for each procedure is described in the paper together with the simplifications adopted for inclusion in the Provisions. Procedures for calculating the effective damping and effective period and higher mode damping ratios for buildings equipped with yielding, viscoelastic, linear viscous, and nonlinear viscous damping devices are presented.
