Optimal damping coefficient of viscous damper in high-level transfer story structure

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 is decomposed to frame -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 mode-superposition response spectrum theory and calculation method of equivalent viscous damping ratio of structure with linear viscous dampers, the calculating formula of optimal damping coefficient of viscous damper of the high-level transfer story structure with viscous dampers is derived. Finally, a sample structure is studied utilizing the above method, analysis results indicate that the proposed formula is valid and the formula is simple and practical.
