Direct displacement-based design for building with passive energy dissipation systems

This paper presents a seismic displacement-based design method for new and regular buildings equipped with passive energy dissipation systems (EDS). Using the substitute structure approach for the building structure and simulating the mechanical properties of the passive energy dissipation devices (EDD) by the effective stiffness and effective viscous damping ratio, a rational linear iteration method is proposed. A target displacement is at first specified and then the corresponding design force, strength and stiffness are obtained. Comprehensive procedures for displacement-based design of several buildings with passive energy dissipation systems are presented. The results are verified by dynamic inelastic time history analysis. Based on the study, it is found that the proposed displacement-based design method is straightforward and can accurately predict the nonlinear behavior of buildings equipped with passive energy dissipation systems.
