<title>Dynamic response-controlled structures with lever mechanisms</title>

Abstract

This paper presents a new seismic response-control system which a new type of toggle mechanism is installed. The one of authors have indicated that the lever mechanism with auxiliary mass can reduce sufficiently the input effect such as earthquake ground motions under the severe condition that the stiffness of lever arm has very high keeping large arm ratios. This paper develops the toggle system in order to overcome this difficulties and derives theoretical formulas of this system. The theory and control effectiveness of the proposed system are confirmed through a series of shaking table test for the model structure with the toggle system.

Seismic Vulnerability Analysis of Prefabricated Concrete Frame with a Cam‐Type Response Amplifying Device of Viscous Damper

“…It had the e ect of amplifying the response of force and displacement, which could make the displacement of the damper far greater than the displacement between the layers of the structure, which solved the problem that the damper could not fully function when the displacement between the layers was small. Later, domestic and foreign scholars used linkage mechanism [7][8][9], gear mechanism [10,11], lever mechanism [12][13][14][15][16], cross-layer support [17,18], etc. to propose a variety of damper response amplification devices.…”
