A simple analysis and design method for damage-controlled buildings and applicable to various damping systems, was developed based on the instantaneous input energy concept. First, energy response characteristics of damper systems were used to derive equations using response spectra to estimate energy dissipation and maximum responses for various damper types. Second, the effect of frame-damper interaction on the overall response was considered for both linear and nonlinear single-degree-of-freedom systems with various types of energy dissipating devices, through frame-damper stiffness and strength ratios. Using the derived energy-based damper relations, a method of estimating response based on the equivalent linear method was shown. Fairly good correlation between dynamic analysis results and response estimates of bilinear Takeda systems with hysteretic dampers were observed. In addition, a theoretical method of deriving optimal damper parameters by maximizing the system's damping ratio is shown, although derived theoretical values are input motion dependent.
