The invention discloses a torsion anti-destabilization device of a buckling-restrained brace, and belongs to the field of building vibration reducing. The torsion anti-destabilization device of the buckling-restrained brace is used for solving the problems that an existing buckling-restrained brace mainly depends on inner core deformation energy consumption resulting in the situation that an innercore is out of action untimely in an earthquake, the replacement and maintenance costs are high, and the self-reset capacity is not achieved. According to the technical main points, the torsion anti-destabilization device is characterized in that the torsion anti-destabilization device comprises torsion springs, limiting clamps and a guiding iron bar, the guiding iron bar penetrates through the energy consumption inner core in the direction perpendicular to the axial direction of the energy consumption inner core and is fixed to the energy consumption inner core, an iron core is exposed on the two sides of the interior of a space, and the torsion springs are connected to the iron core in a covering mode; spring force arms connected with torsion spring bodies are limited by the limiting clamps on the upper side and the lower side of a torsion plane formed when the torsion springs twist, and the torsion anti-destabilization device has the effects that the torsion anti-destabilization device is mounted, and axial load of the energy consumption inner core is borne and dispersed on the spring torsion plane to be borne, so that energy consumption load of the energy consumption inner core is greatly reduced, and the possibility of destabilization of the inner core is reduced, thus the replacing frequency of the inner core is reduced, and the maintenance cost is reduced.

The invention discloses a magnetorheological landing mechanism with repeatable buffering and a buffering method. The mechanism includes an outer cylinder, a cylinder cover, a foot pad, a push rod, a magnetic inner catheter and an outer catheter. The outer cylinder is provided with a piston, which is divided into an upper liquid chamber and a lower liquid chamber; the upper end of the piston is connected with the lower end of the spring, the lower end of the piston is connected with the upper end of the push rod, the piston is provided with two through holes, and the through holes are A magnetic inner conduit and a check valve are provided; the lower end of the push rod is connected with the foot pad; the outer conduit is connected with the upper liquid chamber and the lower liquid chamber, and a check valve is arranged in the middle. The magnetorheological landing mechanism with repeatable buffering of the present invention has the advantages of simple structure, no external energy source, and repeated use.

The invention discloses an in-series disc spring large deformation energy consumption beam column node, which comprises an assembly type column, an assembly type beam and a disc spring combination type damper, wherein the disc spring combination type damper consists of an energy consumption rod, a disc spring set, an internal thread sleeve, an outer sleeve, a sliding guide rod and an extrusion nut, one end of the disc spring combination type damper is fixed on the fixed plate of a surface of the assembly type beam, and the other end passes through the flange plate of the assembly type column and presses tightly the flange plate. By adjusting the pressure of the extrusion nut, tensile deformation generated by the two ends of the disc spring combination type damper can be fully supplied by the energy consumption rod under the action of small and moderate earthquakes, the other part is supplied by the compressive deformation of the disc spring set, so that the disc spring combination typedamper has better deformability, and the fatigue performance of the disc spring combination type damper is conducive to being improved.
