A Study on damping optimization design method of frame-rocking wall structure
For the large vertical displacement between the frame and rocking wall, energy consumption components should be added to protect the main structure. Based on this, additional damping frame-rocking wall is proposed and structural single type of damper amount also could be calculated through the equivalent linearization theory, by defining the objective function, the best damper layout of structure with viscous damper and metal damper which can make the minimum value of the function could be determined, and conclusions are as follows: (1) for the shear-bending structure, the viscous damper can be arranged along the total height of structure when acceleration is considered and the metal damper arranged at two thirds the lower part while the viscous damper arranged at one third the upper when displacement, acceleration and storey drift are considered; (2) for the shearing structure, the metal damper arranged at half the lower part while the viscous damper arranged at half the upper when storey drift is considered, in addition, the metal damper arranged at one third the lower part while the viscous damper arranged at two thirds the upper when displacement, acceleration and storey drift are all considered.
