Vibration control in building engineering is very much in the limelight. This is because the durability of a structure is improved by performing the appropriate vibration control. Vibration control can give the structure the capability to bear complicated external forces, for example, seismic forces, wind forces and so on. The authors are interested in a structure that is able to change its own characteristics, for example, natural frequencies, damping ratios, and so on. When the spring constants of a structure are changed, the resonance points of the structure are changed. The experiment was carried out using sinusoidal waves. We examined a single-degree-of-freedom model that is a variable rigidity structure with a crutch, evaluated the control effect and confirmed that it was good.
