Research on Design Method of Frame-Shear Structures with displacement based dampers
The purpose of this study is to investigate the design method for energy dissipation and seismic reduction of frame-shear wall structures with displacement based dampers.Based on the performance curve method,the initial value of damping parameters of each layer of the structure is determined,the concept of additional damping force center of the structure floor is established,and the optimal position of the additional damping force center is determined by using the optimal control theory.Firstly,the initial values of the damping parameters of each layer of the structure are assigned and grouped once.Then,according to the intelligent algorithm,the secondary distribution and optimi-zation of energy dissipation parameters are carried out on each vertical floor of the structure.Finally,the energy dissipation parameters of the irregular frame shear structure are optimized to the maximum extent under the premise of meeting the seismic performance goals of the re-sult.This method is suitable for the design and optimization of energy dissipation and vibration absorption of displacement damper in other types of irregular structure architecture.
