Abstract
The negative stiffness device can reduce the equivalent stiffness of the structure, and has a good control effect on the peak shear force and acceleration response. The combination with the structural vibration theory makes the negative stiffness device fully play its role, and at the same time improves the seismic capacity of the structure, forming a negative stiffness vibration control device. Through reading and sorting out the research achievements of domestic and foreign scholars, the research progress of negative stiffness devices in the field of earthquake prevention and disaster reduction is discussed from the aspects of theoretical development, effect, device application and development trend, and the future development is prospected.
