TL;DR: Numerical simulation analysis and shaking table test results indicate that isolation control system can effectively overcome the shortcoming due to narrow optimum control band of the passive isolation system, and thus to provide optimal control for different seismic excitations in a wider frequency range.

TL;DR: In this article, a part filling structural frame fabricated joint with a restoration function is presented, where stiffening ribs are symmetrically arranged on two sides of a web of an H-shaped steel column through a segment type part filling steel-concrete combined column, and an open section is internally filled with modular concrete; the upper and lower segment are connected in a tensioning mode through butt joint of an end head box type member and after steel strands penetrate through column end stiffening rib bolt holes.

TL;DR: In this paper, a built-in enhanced variable-damping viscous damping device consisting of a cylinder body, a piston rod and a piston, wherein a sealed cavity defined by the cylinder body and the piston rod is filled with a liquid damping medium, the sealed cavity is divided into a damping cavity body I and a damp-cavity body II through the piston, and the damping cavities I and II are filled with the liquiddamping medium.

TL;DR: In this paper, an external adjustable variable damping viscous damping device consisting of a cylinder body, a piston and a piston rod was designed for vibration attenuation and seismic isolation.
