【 摘 要 】

In this paper, a series of computational analysis is carried out on the united energy dissipation design of the concrete frame structure with the buckling restrained brace and viscous dampers. The calculation results show that the value of the normal lateral stiffness ratio and the additional damping ratio provided the viscous dampers. The relation chart between the two damper matching rules is obtained, which avoids the inconvenience caused by multiple iterations based on the response spectrum design method. The accuracy and practicability of the relation chart for united energy dissipation design are verified by the engineering example. It is proved that the united energy dissipation structure can effectively improve the seismic performance of the whole structure, and has good theoretical research value and practical application value, which can provide some reference for the structure design in high seismic region.
