As shown in Figures 2 to 4, the left side section friction component of energy dissipating section is located on the web of I-shaped friction steel plate 5, as shown in Figures 5 to 7, left side section friction component comprises left side section friction steel plate 7 and for the high-strength bolt 9 of pretightning force is provided, in left side section friction steel plate 7, corresponding high-strength bolt 9 is provided with bolt hole, the shank of bolt two ends of high-strength bolt 9 are connected with left side section friction steel plate 7, and the middle part of high-strength bolt 9 is through the slippage duct 6. of I-shaped friction steel plate 5.
As shown in Figure 14 and Figure 15, in slippage duct 6, leave sufficient size and conform to high-strength bolt 9 shank of bolt sliding curves, making the shank of bolt of high-strength bolt 9 can free slippage in slippage duct 6, to meet the sliding displacement demand of high-strength bolt 9 under earthquake.Determining specifically as shown in figure 14 of slippage duct 6 sizes, under geological process, the shear wall of the left and right sides deflects, when left side shear wall rotational angle theta
1much larger than the right shear wall rotational angle theta
2time, the shank of bolt sliding trajectory of high-strength bolt 9 is a.When left side shear wall rotational angle theta
1equal the right shear wall rotational angle theta
2time, the shank of bolt sliding trajectory of high-strength bolt 9 is b.When left side shear wall rotational angle theta
1much smaller than the right shear wall rotational angle theta
2time, the shank of bolt sliding trajectory of high-strength bolt 9 is c.Because actual shank of bolt sliding trajectory should be between a and c, so slippage duct 6 should live in track a and c envelope.In the present embodiment, the length minimum value in slippage duct 6 is not less than the maximum slippage of high-strength bolt 9, the minimum value of slippage duct width can be according to the situation concrete analysis of two ends shear wall, only need in actual applications rough estimation again slip length and width to be amplified, in the present embodiment, slippage duct 6 width minimum value are the shank of bolt footpath size of the high-strength bolt 9 of 2.5 times.
Consider between the shear wall of left and right and certain level also may occur to relative displacement, and for easy construction, on the basis that is arranged on track a and c in slippage duct 6, expand and simplify, can be reduced to rectangle duct or hourglass shape duct.

In earthquake, left side section friction component and the right section friction component can rotate along with the rotation of left side section shear wall and the right section shear wall; Little earthquake centre, the shearing force that coupling beam is subject to is less, is not enough to overcome the pretightning force of high-strength bolt 9, left side section friction component and the right section friction component do not produce relative sliding, whole coupling beam can be looked as a whole, can limit like this rotation of shear wall, reaches the effect of control structure displacement; Large earthquake centre, the shearing force that coupling beam is subject to is larger, and the pretightning force of high-strength bolt 9 is overcome, and left side section friction component and the right section friction component have produced relative sliding, see Figure 15 (left side section relatively the right section makes progress, and the relative left side of the right section section is downward); If once relatively slippage is △, total frictional force is F, and the seismic energy that a slippage consumes is F △, by slippage ceaselessly, carrys out earthquake energy, reaches the object of damping.
