For the assessment, a structure is modeled as a two-degree-of-freedom system; one degree-of-freedom represents a main structure and the other represents an auxiliary system (i.e., TMD or BID). The hysteretic behavior of the main structure and auxiliary system is approximated by the Bouc-Wen model. A parametric study of linear and nonlinear responses of the system is carried out by using 381 ground motion records, and the ratios of the maximum displacement and ductility demand of the system with auxiliary devices to those without are considered as a measure of effectiveness of TMD/BID. The linear and nonlinear responses are also incorporated for assessing possible damage states and damage costs in the lifecycle cost analysis. The latter is employed as the basis for evaluating the cost-effectiveness of applying TMD and BID in reducing seismic risk.
