Shock absorbing equipment having shear-wall-like mechanism with enhanced damping force for a building and shock absorbing system with the same
A shock absorbing equipment having shear-wall-like mechanism with enhanced damping force for a building includes a longitudinal transmission rod, an upper dampers, and a lower dampers. The two upper dampers are mounted on the upper half wall. Two ends of each of the upper dampers is connected to the upper end of the longitudinal transmission rod and the upper half wall. The two lower dampers are mounted on the lower half wall. Two ends of each of the lower dampers is connected to the lower end of the longitudinal transmission rod and the lower half wall. The shock absorbing equipment sensitively amplifies a displacement between the floors caused by earthquake, so as to early dissipate seismic energy. Moreover, the needed number of the shock absorbing equipment for the building can also be reduced and impact on traffic flow and ambient lighting in the building can be reduced.
1. A shock absorbing device having a shear wall structure with enhanced damping force for a building, the shock absorbing device configured to be installed between an upper beam and a lower beam, an upper half wall extending down from the upper beam, a lower half wall extending up from the lower beam, and the shock absorbing device comprising:
a longitudinal steel plate shear transmission rod extending between the upper beam and the lower beam, configured to swing leftward and rightward across the upper half wall and the lower half wall, and having
an upper end;
a lower end;
a first pivoting portion pivotally connected with the upper half wall; and
a second pivoting portion pivotally connected with the lower half wall;
two upper dampers mounted horizontally on the upper half wall and disposed adjacent to the upper beam, wherein
the upper end of the longitudinal transmission rod is disposed between the two upper dampers,
each of the upper dampers has two opposite ends, and one of the ends of each of the upper dampers is connected to the upper half wall at a position that is proximate to an intersection of the upper beam and an adjacent column that is spaced apart from the upper half wall and the lower half wall and connects the upper beam and the lower beam and a second of the ends of each of the upper dampers is connected to the upper end of the longitudinal transmission rod; and
two lower dampers mounted horizontally on the lower half wall and disposed adjacent to the lower beam, wherein
the lower end of the longitudinal transmission rod is disposed between the two lower dampers; and
each of the lower dampers has two opposite ends, and one of the ends of each of the lower dampers is connected to the lower half wall at a position that is proximate to an intersection of the lower beam and an adjacent column that is spaced apart from the upper half wall and the lower half wall and connects the upper beam and the lower beam and a second of the ends of each of the lower dampers is connected to the lower end of the longitudinal transmission rod.
