Cylinder assembled steel lead damper

Abstract

The invention discloses a cylinder assembled steel lead damper. The damper comprises at least two groups of cylinder assembled lead steel damper units, and each group of cylinder assembled lead steel damper units are connected in series. Each group of cylinder assembled lead steel damper units comprises a cylinder energy consumption body and connecting pieces, wherein each cylinder energy consumption body comprises a lead cylinder and a soft steel cylinder; the soft steel cylinder is arranged on the outer side of the lead cylinder in a sleeving and embedding manner; the connecting pieces are arranged at the two ends of each cylinder energy consumption body. The cylinder assembled steel lead damper has the advantages and the beneficial effects that the rigidity is high; the soft steel cylinder and the lead cylinder have better coordination; the material utilization rate is high; the energy consumption effect is good; the cylinder assembled steel lead damper is mounted by connecting precast components by bolts and nuts; the damping can be adjusted according to requirements; the cylinder assembled steel lead damper is convenient to assemble, easy to construct and controllable in installation quality; each cylinder energy consumption component is high in mechanical performance, and can resist to earthquake actions in all directions, and consume the energy of the earthquake actions in different directions; the cylinder assembled steel lead damper can be used for an earthquake resistant design of a new construction project, and can also be used for the reinforcement and the repair of an existing project.

Description

technical field [0001] The invention belongs to the technical field of vibration control devices for building structures, and in particular relates to a cylinder-assembled steel-lead damper. Background technique [0002] Metallic yielding dampers are various forms of damping energy dissipators made of mild steel or other soft metal materials. Metals have good hysteretic properties after yielding, and use the elastic-plastic hysteretic deformation energy dissipation of certain metals, including mild steel dampers, lead dampers and shape memory alloy (SMA) dampers. The mechanism of its vibration control on the structure is to dissipate part of the energy of the structural vibration through the yield hysteresis energy dissipation of the metal, so as to achieve the purpose of reducing the structural response. [0003] The mild steel damper is to make full use of the good hysteresis characteristics of mild steel after entering the plastic stage. In 1972, American scholars such ...

Problems solved by technology

[0006] The steel-lead damper currently being researched has Chinese Patent No. 200510033467.7, which discloses an invention patent named "Steel-lead Combined Energy Dissipator". The I-shaped plate only has better mechanical performance in the direction of the main axis, and cannot fully utilize the performance of the material. ; Chinese Patent No. 201010282519.5 discloses an invention patent named "a steel-lead damper", which adopts a lead filling process, the lead quality is not easy to guarantee, the coordination between steel and lead is poor, the construction process is complicated, and it is not suitable for standardized production; China Patent No. 201110318337.3 discloses an invention patent named "steel-lead tension-compression damper", which only has better performance in tension and compression; Chinese patent No. 201210448545. "Invention patent, the initial stiffness is small, the effect of the earthquake in all directions, the force effect is general, and the installation is inconvenient

To sum up, the scope of use of these dampers is limited to a certain extent, the mechanical performance of the damper cannot be better exerted, and the installation and connection are inconvenient
