Problems solved by technology
The invention can give full play to the performance of the energy-consuming material itself, and it is easy to replace even if it fails. However, the manufacturing process is complicated and the cost is high because of the use of mild steel. Small energy consumption and no limit function
[0008] The above lead energy dissipators use lead shearing or extrusion to dissipate energy, but there are disadvantages such as small binding force of lead body, easy to be squeezed and laterally bulged to reduce energy dissipating capacity, single energy dissipating form, etc., and do not have Limit function

A lead shear damper with a limiting function comprises an upper cover plate, a lower cover plate, upper side baffles, lower side baffles, partition plates, pins and a lead body, wherein multiple connecting bolt holes are formed in the upper cover plate and the lower cover plate, the two sides of the upper cover plate and the lower cover plate are each provided with one side baffle, gaps are reserved between the upper side baffles and the lower side baffles, the multiple rectangle steel partition plates are arranged between the upper cover plate and the lower cover plate, the partition plates are connected with the side baffles through the pins to form a box-type cavity which is internally provided with unit spaces, and the cavity is filled with molten lead liquid to form the lead body; connecting lines among pin hole centers of the partition plates, and the upper side baffles and lower side baffles are parallel to the cover plate faces. According to the lead shear damper with the limiting function, the structure is simple, the manufacturing cost is low, the manufacture is easy, the composite energy dissipation capacity is strong, and the functions of strengthening the damping effect and shear limiting are achieved.
Description
technical field [0001] The invention belongs to the field of anti-seismic and shock-absorbing civil engineering, in particular to a metal energy dissipator. Background technique [0002] Metals have good hysteretic performance after yielding, and metal yield energy dissipators use various forms of elastic-plastic hysteretic deformation energy dissipation of certain metals, which belong to a type of elastic-plastic energy dissipators, including mild steel energy dissipators. devices, lead energy consumers, etc. From the force form, it can be divided into axial yield type, shear yield type, bending yield type and torsional yield type damper. At present, the common damper products are: X-shaped and triangular dampers, shear-type mild steel dampers, torsion beam energy dissipators, bending beam energy dissipators, U-shaped steel plate energy dissipators, steel bar energy dissipators, rings Energy consumers, stiffening ring energy consumers, etc. Compared with dampers such as ...
