Detailed description of the invention
As shown in Figure 1, 2, a kind of many yield points shearing-type metal damper, comprise upper cover plate 1, lower cover 2, be arranged on power consumption central layer 3 between upper cover plate 1 and lower cover 2, the bilateral symmetry of described power consumption central layer 3 is distributed with power consumption rib block assembly, the assembly in X character form structure that at least three pieces of power consumption rib block assemblies intersections that at least three pieces of power consumption rib blocks that described power consumption rib block assembly is arranged by oblique bottom right and oblique lower-left are arranged form.
The power consumption rib block that described oblique bottom right is arranged is first rib block 4, second rib block 5 and the 3rd rib block 6, and the power consumption rib block that oblique lower-left is arranged is the 4th rib block 7, the 5th rib block 8 and the 6th rib block 9.Described first rib block 4, second rib block 5, the 3rd rib block 6, the 4th rib block 7, the 5th rib block 8 and the 6th rib block 9 are rectangular block structure, and, the shape of first rib block 4, the 3rd rib block 6, the 4th rib block 7 and the 6th rib block 9 is all equal with size, shape and the size of second rib block 5 and the 5th rib block 8 are all equal, further, the length of second rib block 5 is not less than the length of first rib block 4.Described first rib block 4, second rib block 5 and the axis of the 3rd rib block 6 and the angle of upper cover plate 1 are 45 degree to 60 degree, the 4th described rib block 7, the 5th rib block 8 and the axis of the 6th rib block 9 and the angle of upper cover plate 1 are 45 degree to 60 degree, further, first rib block 4, second rib block 5 and the axis of the 3rd rib block 6 are equal with the angle of upper cover plate 1 with the axis of the 4th rib block 7, the 5th rib block 8 and the 6th rib block 9 with the angle of upper cover plate 1.Described first rib block 4, second rib block 5, the 3rd rib block 6, the 4th rib block 7, the 5th rib block 8 and the 6th rib block 9 are low-yield power consumption floor.
During earthquake, when there is opposing parallel shear displacemant distortion with the deformation of member in the upper and lower end plate of damper be installed in structure, drive power consumption central layer 3 that upper and lower horizontal relative shear distortion occurs, thus horizontal shearing stress is produced in power consumption central layer 3, according to mechanics micro unit model, then there is a compressive stress band and tensile stress band respectively, when stress value reaches certain state in ± 45° angle direction, compressive stress band there is flexing phenomenon, show as the out-of-plane buckling distortion of thin plate.
Two stress zones are installed low-yield power consumption rib block, equals to improve stress zone moment of inertia, therefore greatly can improve compressive stress band critical buckling stress value, the generation of flexing phenomenon on normal stress band when preventing Shears for thin sheets shear deformation.When damper generation shear strain, along with the increase of horizontal shear force and shear strain on core plate, axial deformation on oblique normal stress band on power consumption central layer 3 drives its both sides low-yield power consumption rib block generation axial deformation, power consumption rib block deformation values is made to take the lead in reaching yield displacement value, enter plasticity power consumption state, then along with the continuation of damper shearing force and shear strain increases, power consumption central layer 3 stress zone also enters surrender, show as the shear yielding of power consumption core plate, then core plate also enters plasticity power consumption state.Therefore whole damper shows as and successively occurs twice surrender, corresponding two yield shear force values.
