A control structure comprising a pivotably based rocker frame assembly integral with rotary yield units able to produce a constant resistive yield force through high elasto-plastic displacements and high ductilities. Located within and distributed about the rotary yield units are flexural yield plates with particular boundary conditions enabling them to elasto-plastically flex to high cycling elasto-plastic displacements and high displacement and curvature ductilities, while maintaining a constant resistive yield force. The constant resistive yield force produced by the replaceable rotary units enables the control structure to resist and endure extreme seismic events (base motion input) with a constant resistive yield force, while plastic curvatures within the yield zones of the flexural plates of the rotary units are maintained well within their capacity; and forces within the control structure, within its supporting foundations, and within masses or other structures it is seismically supportive of are controlled and limited.

A kinematic seismic isolation device for isolating a superstructure from the movement experienced by a substructure or foundation by providing lateral stability and resistance to stress having a rigid-structure helmet piece with the convex part facing upward and a radius of curvature R; and an intermediate rigid-structure body coupled to the underside of the helmet piece and extends to a bottom end of the device connected by a pivoting connection to the substructure or foundation, wherein the radius of curvature R is greater than or equal to the height H of the device; and wherein a tread plate, which is secured to the bottom surface of the superstructure, rests on the helmet piece.

A multidirectional adaptive re-centering torsion isolator is used for isolating buildings, tanks and bridges from earthquakes. The multidirectional adaptive re-centering torsion isolator includes a flat and/or articulated slider and four or more cylindrical energy dissipaters. The flat and/or articulated slider positioned on top of the column provides vertical load transmission, low friction and horizontal displacement capacity. The cylindrical energy dissipaters provide displacement, re-centering and damping in any of the horizontal directions.

A seismic isolation device comprises an isolation support and an inerter unit arranged on the side of the isolation support, the isolation support having an upper plate and a lower plate, the inerter unit having a rotating rod extending to the side of the lower plate and a flywheel linked with the rotating rod, wherein when the upper and lower plates of the present invention undergo relative displacement due to the occurrence of an earthquake, the inerter unit provide an inertance to reduce the displacement reaction, thereby providing better seismic isolation effect.

An impulse damper device, which is specifically provided for the construction or the dismantling of tall, slim constructions, in particular towers and preferably towers of wind turbines, in order to minimize or eliminate undesired vibration states, which often occur during the construction or taking apart and lead to large increases in the vibration amplitudes of the vibration system. The impulse tuned mass dampers are preferably provided for temporary mobile use, but, in principle, are also suitable for permanent use.

The present invention relates to a seismic isolation device, including: a sliding platform (100) having a sliding surface (120) of a downwardly concave spherical shape formed on an upper surface thereof; and a sliding body (200) placed on the sliding surface (120) being capable of sliding on the sliding surface (120) by means of a sliding means, wherein the sliding body (200) slides on the sliding surface (120) in a situation where an earthquake occurs to effectively absorb vibrations applied to a structure, such that the structure can be safely protected.

A double variable sliding isolator including a bottom sliding plate, a top sliding plate, and a friction piece is provided. The bottom sliding plate has a bottom sliding surface that has at least two curvatures. The top sliding plate is disposed over the bottom sliding plate and has a top sliding surface that has at least two curvatures. The friction piece is disposed between the top sliding plate and the bottom sliding plate and the friction piece is in contact with the bottom sliding surface and the top sliding surface. When an external force is applied to the bottom sliding plate and the top sliding plate, the bottom sliding plate and the top sliding plate will generate a relative displacement, so that the friction piece slides along the bottom sliding plate and the top sliding plate.
