概要	A simplified procedure is proposed for predicting the peak response of a building retrofitted with a low-yield strength steel damper panel considering the strain hardening behavior. To approximate the strain hardening behavior, the use of two models, namely the lower-bound (LB) model and upper-bound (UB) model, is proposed. The predicted peak response of each LB and UB model is predicted through nonlinear static (pushover) analysis and the equivalent linearization technique using the equivalent single-degree-of-freedom model. The predicted peak response of each component is determined from the envelope of the prediction results of LB and UB models. Results show the simplified procedure can satisfactorily estimate the peak response of the retrofitted building model with damper columns considering the strain hardening effect.
