Preliminary Results on the Simulation of Pressurized Sand Dampers by Using the Vaiana-Rosati Model
摘要
This chapter proposes a novel approach to simulate the hysteretic behavior of a pressurized sand damper. In particular, the typical symmetric and pinched force-displacement hysteresis loops exhibited by the tested device are first illustrated. Subsequently, the proposed hysteresis model, denominated Vaiana-Rosati model, is briefly described and adopted to reproduce the device experimental responses.
