Description
ASSEMBLED ENERGY DISSIPATOR WITH VARIABLE STIFFNESS FOR LATERAL CONNECTION OF SHEAR WALLS
TECHNICAL FIELD
This application relates to seismic resistances of buildings, and more particularly to assembled energy dissipators with variable stiffness for lateral connection of shear walls.
BACKGROUND OF THE INVENTION
There is an increasing number of complex high-rise and super high-rise buildings as China’s urbanization rapidly develops, which poses new challenges to earthquake proofing techniques and the durability and shock resistance of structures. Due to higher bearing capacity and deformability, composite shear walls have been widely used in structural systems, but a larger bending deformation will be caused to the shear wall under lateral and vertical forces. When the wall cracks, a relative shear slip deformation will be generated on vertical contact surfaces, and the lateral stiffness and bearing capacity continuously decrease under large and super-large earthquakes, thereby causing the collapse of walls. Therefore, an energy-dissipating and loading device is considered to be added to a deformation focus of the shear wall, but large residential deformation and stress will be caused when the lateral connection of the energy-dissipating device and two adjacent shear walls is in welded manner.
The existing energy-dissipating shear dampers are mainly single-type shear yielding dampers, in which the stiffness of the shear wall stops enhancing after the damper yields, so the reduced bearing capacity and stiffness of the shear wall cannot be enhanced again. At the same time, the single-type yielding shear damper cannot combine the functions of dissipating energy, loading, enhancing stiffness and separating the functions of dissipating energy and loading.
SUMMARY OF THE INVENTION
11854774_1 (GHMatters) P112366.AU

The threshold control device is realized by means of bolt holes provided on the steel plates of the stiffness enhancing zone and connecting with the buckling-restrained plates. The bolt holes on the adjacent steel plates are different in diameter, and a bolt hole on a side of the steel plates of the stiffness enhancing zone is larger than a bolt rod in diameter.
A bolt hole on one of the steel plates of the stiffness enhancing zone fits a rod portion of the bolt, and a diameter of a bolt hole on the other one of the steel plates of the stiffness enhancing zone is 2-3 mm larger than the diameter of the rod portion of the bolt.
The end plates are provided with slide rails fitting the steel plates of the stiffness enhancing zone, and the slide rails are configured to avoid out-of-plane buckling of the steel plates.

DETAILED DESCRIPTION OF EMBODIMENTS
The present invention will be further illustrated below with reference to the accompanying drawings.
Example 1
As shown in FIG. 1, illustrated is an assembled energy dissipator with variant stiffness for lateral connection of shear walls, comprising a stiffness enhancing zone 15, an energy-dissipating zone 14 and end plates 2. The energy-dissipating zone comprises mild steel plates of the energy-dissipating zone 5, bolts 6 and bolt connection plates 4. The stiffness enhancing zone comprises an upper steel plate 7 and a lower steel plate 8, bolt holes of the upper steel plate 11, bolt holes of the lower steel plate 12, two buckling-restrained plates 9, high-strength bolts 10 and slide rails 13.
As shown in FIG. 2, the energy-dissipating zone 14 is provided outside the damper, and the stiffness enhancing zone 15 is provided inside the damper. The bolt connection plates on an inner side of the energy-dissipating zone 14 have the same height with the end plates, and are arranged on two sides of the steel plates of the energy-dissipating zone and are welded to the end plates. A gap is arranged between the bolt connection plates on an outer side of the energy-dissipating zone which have the same height and quantity with the steel plates of the energy-dissipating zone. The bolt connection plates on the outer side of the energy-dissipating zone are arranged on
11854774_1 (GHMatters) P112366.AU two ends of the steel plates and are not welded to the end plates. The steel plates of the energy-dissipating zone 5 are connected to the bolt connection plate via bolts 6. The bolted connection effectively avoids local stress concentration and residual deformation, and realizes the detachable replacement of the mild steel of the energy-dissipating zone. The steel plates of the stiffness enhancing zone are connected with the pre and post buckling-restrained plates via high-strength bolts. A side of the upper steel plate is welded to a left or right end plate, and a side of the lower steel plate is welded to a right or left end plate. A gap is respectively arranged between the other side of the upper steel plate and the left or right end plate and between the other side of the lower steel plate and the right or left end plate. The slide rails 13 capable of restraining the bucking of the steel plates are provided at front and back sides of the steel plates of the stiffness enhancing zone.
As shown in FIG. 3, the bolt connection plates of the energy-dissipating zone are arranged at right and left ends of the mild steel plate of the energy-dissipating zone. One bolt connection plate having the same height with the end plates is welded to the end plates, and the other bolt connection plate is not welded to the end plates, and gaps are provided on welding sides of the end plates. The gaps have the same length with the gap between the mild plates, so that a sufficient space is provided to allow the deformation of the steel plates of the energy-dissipating zone to dissipate the seismic energy and to disassemble the mild plates. Thus, the mild steel plates are replaceable, which is low-carbon, energy-saving, green, ecological and sustainable.
As shown in FIGS. 4A-B and 5, the steel plates of the stiffness enhancing zone comprises an upper steel plate 7 and a lower steel plate 8. The upper and lower steel plates connect with the buckling-restrained plates in parallel via the high-strength bolts. The threshold control device is realized by means of bolt holes (bolt holes of the upper steel plate 11 and the lower steel plate 12). A diameter of the bolt holes of the upper or lower steel plate is 2-3 mm larger than a diameter of the bolt holes of the lower or upper steel plate, so the mild steel plates of the energy-dissipating zone firstly dissipate energy, and the stiffness enhancing zone enters the secondary stiffness
11854774_1 (GHMatters) P112366.AU enhancing stage after the mild steel plate yields. The slide rails are respectively arranged at the sides of the steel plates having the gap. When entering the stiffness enhancing stage, due to the lacking of planar constraint, the upper and lower steel plates buckle while suffering a force, but the slide rails are capable of effectively enhancing the planar constraint of the upper and lower steel plates, so the secondary stiffness enhancing is fully achieved by the upper and lower steel plates.
The energy dissipating and the stiffness enhancing of the energy-dissipating damper with variant stiffness for lateral connection are designed to be carried out in stages. The steel plates of the energy-dissipating zone can be used for dissipating energy and providing an initial stiffness, and are easy to be disassembled and replaced. A deformation threshold is set for the steel plates of the stiffness enhancing zone. When a deformation is beyond the deformation threshold, two adjacent shear walls enter a second stage in which they work together, and are capable of enhancing the lateral bearing capacity when it reduces after reaching a peak value.
