Performance design method of a new combined isolation system based on passive variable damping variable stiffness device
Passive variable damping and stiffness device is a device that does not require external energy input and feedback control,and has the functions of variable damping energy consumption and variable stiffness limit.By combined with isolation bearings,this device forms a new isolation system that can effectively control seismic waves of different types and intensities.Based on the theory of performance-based design,a design method for composite isolation systems has been proposed.Through this method,the parameter design of passive variable damping and stiffness devices and isolation bearings in the isolation layer can be completed.The study also provided a complete design process and detailed explanation of the design process,and verified the feasibility and effectiveness of the design method through engineering examples.This performance design method can be widely applied in the engineering design field of composite isolation new systems,providing a reliable design method and technical support for related engineering.Through this advanced design method,the structure can better cope with disasters caused by earthquakes,ensuring the safety and stability of the structure.
