Graded energy dissipation device
The invention discloses a graded energy dissipation device which comprises a first base and a second base. The first base and the second base extend longitudinally in an opposite direction until the upper half part of the first base and the lower half part of the second base are staggered side by side; the two ends of a first yield energy dissipating part are respectively and fixedly connected tothe middle part of the second base and the upper part of the first base; one of the bottom of the second base and the middle part of the first base is fixedly connected with one end of a second yieldenergy dissipating part, and the other of the bottom of the second base and the middle part of the first base is slidably connected with the other end of the second yield energy dissipation part in the longitudinal direction in a directional mode; when the first yield energy dissipating part yields and deforms under small shocks, because one end of the second yield energy dissipating part is longitudinally and slidably connected to the first base or the second base in a directional mode, the first base and the second base cannot apply stress which deforms the second yield energy dissipating part to the second yield energy dissipating part; and the relative displacement of the first base and the second base during moderate and large earthquakes is greater than the sliding range of the longitudinal directional sliding, so the first yield energy dissipating part and the second yield energy dissipating part yield and dissipate energy together.
本发明公开了一种分级消能器，包括第一基部和第二基部；第一基部和第二基部纵向相向延伸至第一基部的上半部分和第二基部的下半部分并排相错；第一屈服耗能件的两端部分别固定连接第二基部的中部与第一基部的上部；第二基部的底部与第一基部的中部二者中，一者与第二屈服耗能件的一端部固定连接，另一者与第二屈服耗能件的另一端部沿纵向定向滑动连接。第一屈服耗能件小震屈服变形时，因第二屈服耗能件一端纵向定向滑动连接第一基部或第二基部，导致第一基部和第二基部尚无法向第二屈服耗能件施加令其变形的应力；而中大震时第一基部和第二基部的相对位移大于前述纵向定向滑动的滑动范围，因此第一屈服耗能件和第二屈服耗能件共同屈服耗能。
