FUNDAMENTAL CHARACTERISTICS OF JOINT DAMPER REPRESENTED BY MAXWELL MODEL BASED ON POLE ALLOCATION

For two adjacent buildings connected by a joint damper, an inverse problem is formulated based on the pole allocation method in control theory. Each building is simplified as a single-degree-of-freedom lumped-mass damped shear model, and the joint damper is represented by the Maxwell model that consists of a dashpot and joint spring in series. The model is useful for understanding the realistic effectiveness of vibration reduction. The previous study considers only a dashpot as the joint damper, while the present study considers the dashpot and joint spring. The difference between the two models is discussed under the same control target.
