In such a joint structure, it has been attempted to use a friction damper having an energy absorbing function in order to secure a proof stress that can cope with a wide range from a small-scale earthquake to a large earthquake. The friction damper is
A hysteretic damping damper showing the hysteretic characteristics of rigid-plastic deformation,
The load deformation curve draws a loop to try to damp the vibration, and the area of the hysteresis loop corresponds to the energy absorbed during one cycle. As an example of such a friction damper, the friction plate material and the sliding plate material are clamped by high-strength bolts, and the damper function is exerted by the frictional force generated between the two plates, which is relatively inexpensive to manufacture and maintenance and inspection. A simple friction welding type energy absorption structure is known.

When a tensile force is applied to this friction-bonding type energy absorbing structure and the frictional force generated between the friction plate and the sliding plate is exceeded, the sliding plate has the shaft portion of the high-strength bolt in one wall of the slot hole. You can move until you hit. Further, when a compressive force is applied, the shaft portion of the high-strength bolt can move until it abuts the other wall of the slot hole. Therefore, when the tensile force and the compressive force act on the sliding plate exceeding the frictional force between the sliding plate and the sliding plate, the sliding plate expands and contracts by maximizing the length obtained by subtracting the shaft diameter of the high-strength bolt from the length of the slot hole. Since it is possible, there is an advantage that it is possible to absorb energy from a small earthquake to a large earthquake depending on the dimension selection of the slot hole.

Such a friction welding type energy absorbing structure is, for example, a high-strength bolt friction joining structure of a box-shaped cross-section column and an H-shaped cross-section beam, or a high-strength bolt of an H-shaped cross-section material and an H-shaped cross-section material. Although it can be applied to a friction welding structure, in order to secure the necessary strength of the welding structure, it is necessary to increase the friction surface, which necessitates an increase in the number of friction plates and sliding plates, which complicates the welding structure and reduces the construction load. In addition to the increase, there is a problem that the material cost increases.

Since the high-strength bolt friction joint structure of the present invention is equipped with a hysteresis damping type friction damper, the load deformation curve draws a loop to damp vibrations, and main vibrations of columns, beams, etc. The stress and deformation on the material can be reduced, and as a result, the relative proof stress of the joint structure can be improved. For example, when the attachment plate is used, the bolt hole of the attachment plate is a slot hole (here, it means a long hole in which the axial diameter of the H-shaped cross-section material is a long diameter. Hereinafter referred to as “slot hole”). Then, when a load is applied to the H-shaped cross-section material and slippage occurs over the maximum frictional force generated between the addition plate and the friction plate and between the addition plate and the H-shaped cross-section material, the shaft of the high-strength bolt is In the process in which the part moves within the slot hole for a certain distance, it is possible to stably transmit the stress close to the maximum frictional force at the joint part due to the sliding friction due to the addition of the friction plate.

In this type of high strength bolt friction welding,
In order to smoothly insert the high-strength bolt into each bolt hole, the bolt hole should be a perfect circle, and the hole diameter should be 2 times larger than the shaft diameter of the high-strength bolt.
Although it is set to be about 3 mm larger, in the present invention, the bolt holes of the friction plate and the bolt holes of the H-shaped cross-section member are provided on the assumption that the friction plate is brought into contact with the outside of the attachment plate and fastened with high-strength bolts. The bolt hole is made as small as possible in comparison with the conventional hole diameter so that the bolt can be inserted, and the bolt hole in the region where the friction plate of the addition plate comes into contact is made a slot hole. This slot hole is applied to the bolt holes of the attachment plate and the joint angle, but it is not a necessary condition to make all the bolt holes slot holes. For example, only one H-shaped cross-section material side may be slot holes. . In consideration of clarification of structural performance, processing cost, workability, etc., it is often advantageous to use only the bolt holes on one H-shaped cross-section material side as slot holes.

The major axis of the bolt hole which becomes the slot hole is preferably set to about 1.5 to 2.5 times the diameter of the high strength bolt. Long diameter is 1.5 mm of high strength bolt shaft diameter
If it is less than the above, the damping effect due to sliding friction is not sufficient. In addition, there is a limit to the damping effect due to sliding friction, and even if the major axis exceeds 2.5 times the shaft diameter of the high-strength bolt, it does not lead to an improvement in the yield strength of the joint structure as a whole, thus reducing the cross section and increasing the processing cost. Considering the above, it is not a good idea to make the diameter of the high strength bolt more than 2.5 times. However, this condition can be set in consideration of the strength of each member, the frictional force on each friction surface, the load, the target value of damping, and the like.

The friction plates that come into contact with the outside of the attachment plate or the joint angle are independently added to each high-strength bolt inserted through each slot hole of the attachment plate or the joint angle, and a friction additional washer (having a larger friction surface than a normal washer) is provided. It is more effective from the viewpoint of saving the material cost and efficiently securing the sliding friction, as described above. The shape of this friction plate is mainly square or circular. It is preferable to set the diameter of the bolt hole to be as small as possible within a range where the bolt can be inserted. It is disadvantageous to use a single friction plate for a plurality of high-strength bolts because it is very difficult in terms of bolt insertion in terms of construction and increases costs. As the high-strength bolt used in the present invention, a well-known high-strength bolt such as a torcia-type high-strength bolt or a high-strength hexagonal bolt having a torque control mechanism at the tip on the nut screwing side can be used. In order to control the slippage phenomenon at each joint surface, it is also effective to subject the joint surface to a high friction treatment that gives a slip coefficient of 0.6 or more.

According to the present invention, for example, the flange of the H-shaped cross-section beam is arranged so as to abut against the web of the split tee attached to the box-shaped cross-section column, and the H-shaped cross-section beam 4 is provided through the attachment plate and the joint angle. In the case of high-strength bolt connection, for example, the bolt hole on the H-shaped cross-section beam side is made into a slot hole, a load acts on the H-shaped cross-section beam 4, each addition plate, a friction additional washer, and a flange of the H-shaped cross-section beam. When slippage occurs due to the friction force generated between them, during the process in which the shaft portion of the high-strength bolt moves within the slot hole of each attachment plate for a certain distance, especially due to sliding friction due to the addition of a friction additional washer The stress close to the maximum frictional force can be stably transmitted at the joint. As a result, it is possible to prevent damage to the main material such as a box-shaped cross-section column and an H-shaped cross-section beam during an earthquake, etc., and improve the safety of the entire structure. Further, for example, in the case where the split tee attached to the box-shaped cross-section column is arranged so as to abut against the H-shaped cross-section beam, and high-strength bolt connection is performed through the joint angle and the attachment plate, the H-shaped cross-section column is used. When attaching the cross-section beam, the position of the joint angle and the attachment plate can be easily adjusted, and the restrictions at the time of the work of adjusting the position of the H-shaped cross-section beam are relaxed and the workability is improved.
