A visco-plastic device for seismic protection of structures

Dimensional analysis of the slotted bolted connections against impulsive earthquake ground motions

“…Consequently, the passive control systems such as the metallic and various hysteretic dampers were invented to dissipate energy without power sources [6][7][8][9]. In most passive control systems, such as a metallic plate damper or a Buckling Restrained Brace (BRB), the input energy is dissipated by sacrificial elements which are replaceable after the earthquakes [10][11][12][13][14].…”

A hybrid passive control device for steel structures, I: Development and analysis

“…Initial work in hybrid passive control devices utilizing both rate dependent and rate independent devices include the ViscoHyperelastic Device [13] and the Visco-Plastic Device (VPD) [14]. Both devices use a combination of HDR and a metallic yielding element configured in a unique geometry.…”

A hybrid passive control device for steel structures, II: Physical testing

“…Work on hybrid passive devices includes the Visco-Plastic Device (VPD) and the Visco-Hyperelastic Device [15,16]. The VPD consists of two curved plates or channel sections sandwiching a block of high-damping rubber material.…”
