Abstract： Based on the limited demand of inter-story drift and equivalent lateral rigidity ratio of high-level transfer story structure in Technical Specification for Concrete Structures of Tall Building and Code for seismic design of buildings, the calculation model that the high-level transfer story structure with BRBs is decomposed to frame with BRBs -shear wall structure below the transfer story and shear wall structure above the transfer story of equivalent lateral rigidity ratio has been adopted. Then, based on the above model, the calculating formula of elastic stiffness and simplified design method for BRB of the high-level transfer story structure with BRBs is derived. Finally, a sample structure is studied utilizing the above method, analysis results indicate that the proposed formula and method is valid and may be as a reference to the high-level transfer story structure with BRBs.
