Abstract: This paper proposes an energy dissipation structure design methodology based on equivalent linearization and equivalent base-shear methods in reference to Japanese design practice and Chinese design codes. Schematic procedure of the methodology is as follows: 1) Set basic parameters of the structure according to the structural performance targets and design experiences, and choose appropriate dampers; 2) Calculate the equivalent stiffness and damping of the dampers using equivalent linearization method; 3) Calculate the seismic responses of the equivalent linearization structure using equivalent base-shear method; 4) Repeat step 1) to 3) until the structure meets the performance targets; 5) Use time history method to finally verify the design results. This paper proposes the basic principles and implementation of the energy dissipation structure design methodology, and its effectiveness is proved through a specific engineering example.
Key words: engineering structure; energy dissipation; structure design; equivalent linearization; equivalent base-shear method; damper
