Abstract
A damping building structure, in the form of a floor joist, spanning two separated supports. Oscillations in the joist are damped by a pair of overlapping plates which are clamped together by one or more nuts and bolts. One of the plates is secured to the floor joist being damped, and the other of the plates is secured, directly or indirectly, to ground. The friction between the overlapping plates acts to damp any oscillations in the floor joist. A spring may be interposed between one of the plates and the nut or bolthead, and, if desired, a friction material may be sandwiched between the plates. The damping arrangement may be secured to the floor joist at one end, at both ends, or at mid-point of the span between the two supports.
