The invention relates to a friction-elliptical soft steel bar composite damper. The friction-elliptical-shaped soft steel bar composite damper comprises an upper connecting steel plate, a friction plate, a middle connecting plate, elliptical section soft steel bars and a lower connecting steel plate, wherein the upper connecting steel plate, the friction plate, the middle connecting plate, the elliptical section soft steel bars and the lower connecting steel plate are sequentially arranged from the top to the bottom, a plurality of horizontal groove strip holes are formed in the upper connectingsteel plate, a plurality of first mounting through holes in one-to-one correspondencewith the horizontal groove strip holes are formed in the friction plate, a plurality of longitudinal groove stripholes in one-to-one correspondence with the horizontal groove strip holes are formed in the middle connecting plate, the upper connecting plate, the friction plate and the middle connecting plate areconnected by a bolt and a nut on the bolt, and wherein the boltsequentially and vertically penetrates through the horizontal groove strip holes, the first mounting through holes and the longitudinalgroove strip holes; and the top ends of a plurality of elliptical section soft steel bars are connected with the lower surface of the middle connecting steel plate, and the bottom ends of the elliptical section soft steel bars are connected with the upper surface of the lower connecting steel plate. The friction-elliptical soft steel bar composite damper has simple structure.
Description
technical field [0001] The invention relates to a friction-elliptical soft steel rod composite damper and its working method. Background technique [0002] At present, most of the researches only focus on a single damper, and cannot carry out staged energy consumption. At present, most studies on mild steel dampers use steel plates, which can only dissipate energy in one direction, and cannot dissipate energy in two directions. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a friction-elliptical mild steel rod composite damper and its working method, which are not only simple in structure, but also convenient and efficient. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a friction-elliptical mild steel rod composite damper, including an upper connecting steel plate, a friction plate, a middle co...
