Controllable strain amplitude energy dissipation steel damper
The invention relates to a controllable strain amplitude energy dissipation steel damper which comprises a first flat plate and a second flat plate which are vertically arranged in parallel, the first flat plate is connected with a main beam, the second flat plate is connected with a pier or a bent cap, and a plastic energy dissipation assembly is arranged between the first flat plate and the second flat plate. The plastic energy dissipation assembly comprises plastic energy dissipation strips alternately wound on the first flat plate and the second flat plate, the two ends of each plastic energy dissipation strip are fixedly connected with the second flat plate, and when an earthquake occurs, the first flat plate and the second flat plate generate relative dislocation; and the plastic energy dissipation strips plastically deform and limit the relative displacement of the first flat plate and the second flat plate. Compared with the prior art, the damper is controllable in strain amplitude, adjustable in maximum stroke, good in fatigue performance, suitable for strong earthquakes, simple in structure, high in economical efficiency and convenient to maintain after earthquakes, only bolts of the first flat plate and the second flat plate need to be screwed off, the plastic energy dissipation strips need to be replaced, and the damper is suitable for application and popularization.
本发明涉及一种可控应变幅耗能钢阻尼器，该阻尼器包括上下平行放置的第一平板和第二平板，第一平板与主梁连接，第二平板与桥墩或盖梁连接，第一平板和第二平板之间设有塑性耗能组件，塑性耗能组件包括交替缠绕在所述第一平板和所述第二平板上的塑性耗能条带，且塑性耗能条带的两端与第二平板固定连接，当地震时，第一平板与第二平板发生相对错动，塑性耗能条带发生塑性形变且限制第一平板与第二平板的相对错动。与现有技术相比，本发明阻尼器应变幅可控，最大行程可调，疲劳性能较好，适用于强震情况，且构造简单，经济性强，震后养护维修方便，仅需拧下第一平板以及第二平板的螺栓，重新更换塑性耗能条带即可，适合推广和应用。
