The objective of this investigation is to improve the fundamental understanding of how and why nonlinear fluid viscous dampers (FVDs) and nonlinear viscoelastic (VE) dampers are effective in reducing structural response and to develop simplified analysis and design procedures for practical applications of these dampers. An innovative technique is developed for single-degree-of-freedom (SDOF) systems, which is then extended to asymmetric one-story, 2-degree-of-freedom systems. directly from the earthquake design spectrum for an asymmetric one-story system with nonlinear VE dampers.
