How to reinforce with steel braces. A method of reinforcing an earthquake-resistant wall with a steel plate is used as a general method and means. On the other hand, embodiments of the reinforcing method are roughly classified into a method of reinforcing the outer peripheral portion (outer shell) of the existing building and a method of reinforcing the inside of the existing building. The former has a drawback that it blocks the opening of the building and deteriorates the livability. The latter not only reduces the working space and living space in the building, but also reduces the noise when installing the formwork during the construction, placing the concrete, and then installing the construction anchor. "
There is a disadvantage that it cannot be reinforced.

There is a method of attaching and reinforcing. However, the above method requires a long construction period. In the above method, the weight of the Pca member is huge and the workability is poor. According to the above-mentioned method, if the existing building is RC or SRC, the rigidity of the existing column-beam frame is high, so it is inevitable to use a brace and a steel plate-based reinforcement structure. There is a disadvantage that the properties are deteriorated.

３を繋いだ繋ぎ桟である。According to the present invention, the steel column 3 as a reinforcing member may be configured and implemented as a composite of a normal steel portion and an extremely low yield point steel portion serving as a vibration control element (vibration control device). It is. In the case of the embodiment shown in FIGS. 1A and 1B, two steel columns 3 as reinforcing members are arranged along both sides of one existing column 1 constituting the outer shell frame of an existing building. It is attached in parallel (however, two or more columns are also possible). A part incorporating the ordinary steel plate 5 between the two columns 3, 3 and an extremely low yield point steel plate 6 (vibration control element) It is configured as a complex with the part incorporating the vibration device. However, in place of the ordinary steel plate 5 and the extremely low yield point steel plate 6 serving as a vibration damping element, a composite having a configuration in which braces made of each material are incorporated may be used. Reference numeral 9 in FIG. 1A denotes left and right columns 3 at the boundary between the ordinary steel plate 5 and the extremely low yield point steel plate 6.
It is a connecting pier connecting three.

After that, the space (groove) of the steel beam 4 arranged so as to accommodate the head of the construction anchor 7 is densely filled with the non-shrinkable grout 8 and integrated and attached. In this case, a stud is provided on the side of the steel beam 4 as shown in FIG.

の吸収効果を高めるのである。The behavior of the reinforcing column 3 during an earthquake in the vibration control method shown in FIG. 1 is exaggerated as a conceptual diagram in FIGS. 2A and 2B. When the extremely low yield point steel portion 6 (vibration control device) is deformed in the elastic range, the horizontal deformation of the reinforcing column as a whole changes linearly in the height direction as shown in FIG. 2A. When the extremely low yield point steel portion 6 yields, as shown in FIG. 2B, the extremely low yield point steel portion 6 yields before the ordinary steel portion 5 due to a difference in the yield point from the ordinary steel portion 5. From the point of yield, horizontal deformation (interlayer deformation angle) concentrates on the extremely low yield point steel portion 6. However, since the ordinary steel portion 5 still remains in the elastic range, the deformation is concentrated on the extremely low yield point steel portion 6 and locally large deformation occurs, thereby enhancing the effect of absorbing seismic energy.

上記同様の作用効果を得ることができる。The existing building and the steel frame reinforcing member transmit the seismic force to the steel column 3 by the steel beam 4 integrated by the post-installed anchor 7 and the like. The bending moment generated by the shearing force applied to the steel column 3 as the reinforcing member is borne by the steel beam 4. Since it is up to the above, the steel column 3 as a reinforcing body has a composite structure as shown in FIG.
Even when one column itself is implemented in a configuration in which the column material of the extremely low yield point steel portion and the column material of the ordinary steel portion are joined in series,
The same operation and effect as described above can be obtained.

The two steel columns 3, 3, which are reinforcing members, are attached in parallel at an interval of the full width to the opening edges of the left and right sleeve walls 10, 10. Between these two steel columns 3, 3, horizontal crossbars 9, 9 are attached at two places (however, not limited to three) that divide the floor height of the pillar 3 into approximately three equal parts.

In the other frame, a steel plate 5 made of ordinary steel and having a thickness of about 20 mm is incorporated to form a composite structure.

In addition to installing the post-installed anchor 7 on the existing beam 2 as a means for integrally attaching the existing beam 2 constituting the outer shell frame of the existing building, the steel beam 4 is also provided with a stud 11 to be embedded in the grout. This shows a configuration that enhances the effectiveness of integration.
