Abstract

<p>Mechanical properties of new hysteresis damping device using thin steel plates are investigated by finite element analysis (FEA) and full-scale experiments. As the result of FEA with shapes of steel plate as main parameter, steel plates with origami inspired three-dimensional resistance mechanisms show better stiffness, yield load, and more plasticized area than with flat shapes The experimental results agreed well with the FEA results by improving joints to prevent brittle fractures.</p>
