The invention discloses a multi-plane quasi linear energy dissipating damper, and relates to the energy dissipating damping technical field in civil engineering; a hollow steel round bar is arranged in a crossing portion between a second steel round bar and a fourth steel round bar, and arranged on the second steel round bar; two ends of a first steel round bar, the second steel round bar, a third steel round bar and the fourth steel round bar are respectively provided with a hinged steel plate; tops of the first to fourth steel round bars are respectively arranged on a reinforcing rib of a lower portion of a lower steel plate through the hinged steel plates; the first to fourth steel round bars are respectively sleeved by a steel cylinder with an inner thread. Compared with an existing dissipating energy damping composition, the multi-plane quasi linear energy dissipating damper is light in weight, strong in absorption capability, stable, and has energy dissipating damping function for seismic waves from any direction, thus providing multidirection omnibearing energy dissipating damping function; the multi-plane quasi linear energy dissipating damper is suitable for various large span space structures, reasonable in design, simple in structure, and wide in application scope.

Description

Technical field: [0001] The invention relates to a multi-plane quasi-linear energy-dissipating shock absorber, which belongs to the technical field of energy-dissipating and shock-absorbing structures in civil engineering. Background technique: [0002] The main components of existing energy dissipation and shock absorbing devices are divided into two parts: support components and energy dissipation components. The support components are mostly heavy-duty structures such as section steel; Deformation and axial tension and compression deformation. The main problems or defects existing in the existing energy dissipation shock absorber: 1) The non-energy-consuming support parts are mostly shaped steel, which has a large dead weight, a large additional bearing capacity to the main structure, and high cost. In addition, due to the axial The pressure is generated, so the influence of the buckling problem needs to be considered, which brings great troubles to the design; 2) The yi...

Problems solved by technology

The main problems or defects existing in the existing energy dissipation shock absorber: 1) The non-energy-consuming support parts are mostly shaped steel, which has a large dead weight, a large additional bearing capacity to the main structure, and high cost. In addition, due to the axial The pressure is generated, so the influence of the buckling problem needs to be considered, which brings great troubles to the design; 2) The yield deformation of the metal component is used as the energy-dissipating part, the deformation is relatively unstable, and there is slippage, which has a great impact on the energy-dissipating capacity ; 3) The energy dissipation and shock absorption effects are only good for one-way, but the randomness of the earthquake leads to uncertainty in the input direction of the seismic wave

In this way, the shock absorption effect of the current energy dissipation shock absorber on the overall structure will be affected to varying degrees
