Multidirectional energy dissipation corrugated pipe damper
The invention relates to a multidirectional energy dissipation corrugated pipe damper, and belongs to the technical field of structural engineering energy dissipation and shock absorption. The metal damper is composed of an inner corrugated pipe, an outer corrugated pipe, an upper end plate and a lower end plate. According to the multidirectional energy dissipation corrugated pipe damper, the design concepts of multidirectional energy dissipation, improvement of the shear bearing capacity of the damper, inhibition of out-of-plane buckling, improvement of structural rigidity and the like are applied, and the limitation that a traditional shear type metal damper can only dissipate energy in a plane and cannot dissipate energy in other directions is broken through. The damper has good shear bearing capacity and is uniform in stress. Due to the arrangement of the corrugated pipes, the damper basically does not bear vertical force, and the energy dissipation performance is stable. Comparedwith a U-shaped damper, the steel consumption is reduced when the yield bearing capacity is the same, the economic benefit is obvious, and the normal use function of the damper can be recovered only by replacing energy dissipation parts after an earthquake. The corrugated pipes are high in lateral rigidity, the overall rigidity of the structure can be improved, and structural earthquake response is reduced. The two ends of the inner and outer corrugated pipes of the metal damper are welded to the end plates, replacement is easy and convenient, the metal damper can be effectively combined witha shock insulation support, and lateral force is provided for the support.
本发明涉及一种多向耗能波纹管阻尼器，属于结构工程消能减震技术领域。该金属阻尼器由内外波纹管、上端板和下端板组成。本发明应用多向耗能、提高阻尼器抗剪承载力、抑制面外屈曲、提高结构刚度等设计理念，打破了传统剪切型金属阻尼器只能在平面内耗能，无法在其他方向耗能的局限性。该阻尼器具有良好的抗剪承载力，受力均匀；波纹管的设置可使阻尼器基本不承担竖向力，耗能性能稳定；相比U形阻尼器，屈服承载力相同时降低用钢量，经济效益明显，震后仅更换耗能部件即可恢复阻尼器正常使用功能；波纹管抗侧刚度大，可提高结构整体刚度，减轻结构地震反应。该金属阻尼器内外波纹管两端与端板焊接，更换简便，可与隔震支座有效结合，为支座提供侧向力。
