Abstract: A construction steel platform system using a tuned liquid damper (TLD) and a tuned mass damper (TMD) for composite tuned damping is provided. According to the construction steel platform system using a TLD and a TMD for composite tuned damping, a composite damper is composed of the TLD and the TMD overlapping each other, and a construction steel platform is placed above the double dampers. By adjusting a hole diameter of a partition plate in the TLD, a liquid level in a water tank, a stiffness of a spring at an edge of a friction support and mass of materials of a top of the steel platform, the whole steel platform system can achieve composite tuned damping. The TLD and the TMD can be flexibly combined in series or in parallel according to requirements of actual wind and earthquake loads.

Abstract: A bottom corner damper with a displacement amplification function and a fabricated type shear wall with rocking energy dissipation are provided. The fabricated type shear wall with rocking energy dissipation is composed of a precast shear wall, upper connecting plates, middle connecting plates, lower connecting plates, bent steel plates, bolts, upper support arms, lower support arms, connectors, lead screws, cylinder barrels, viscous fluids, and propellers. A fabricated type shear wall structure, where novel dampers with displacement amplification and steering functions are installed at weak parts of the bottom of the shear wall, the novel dampers are composed of bending energy dissipation dampers, displacement amplification and steering devices and viscous energy dissipation dampers, and the novel dampers have the functions of amplifying the displacement and converting force in a vertical direction of the structure into force in a horizontal direction for transmission.
