DEVELOPMENT OF HYSTERESIS DAMPER FOR WOODEN HOUSES INSPIRED BY ORIGAMIC THREE-DIMENSIONAL RESISTANCE PART 1: CONSIDERATION ON BASIC SHAPE MODEL

Abstract

Mechanical properties of new origami inspired reinforcing and hysteresis-damping device using thin steel plates are proposed and investigated. Results of FEA and full-scale experiments are indicated and discussed. FEA showed better stiffness, yield strength and efficient plasticized area of the device than simple flat pates, due to three-dimensional geometrical resistance system. The experimental results agreed well with the FEA results. Damping of the device is also examined and discussed.
