As non-limitingly illustrated in FIGS. 1, 2 and (3), a method of connecting a structure according to at least one embodiment of the present invention includes gussets 10 fixed to each of columns 2 or beams 3 and , a brace 20 connected to the gusset 10, an interposing step S10 of interposing the connecting member 30 between them, and a mounting step S20 of mounting the brace 20 to the gusset 10 via the connecting member 30.
It should be noted that the gusset 10 shown in the present disclosure may include, for example, the single gusset shown in FIG. 1 or the double gusset shown in FIG. Joining using a single gusset is a method of joining so-called H-shaped steel so that the strong axis direction is directed in the frame plane, and joining with the brace 20 is performed using one gusset plate. Joining using double gussets is a method of joining with the weak axis direction of the H-shaped steel facing the inside of the frame plane, and joining with the brace 20 is performed using two gusset plates.

In the mounting step S20, the first connecting end portion 12 provided on the gusset 10 and the one end 31 of the connecting member 30 are joined, and the second connecting end portion 22 provided on the brace 20 and the other end 32 of the connecting member 30 are joined together. The gusset 10 and the brace 20 are connected by joining the .
The gusset 10 may include wing plates 11 (corresponding to flanges of so-called H-beams in FIG. 1 and webs in FIG. 2) perpendicular to the gusset plate along the longitudinal direction X of the brace 20.
According to the above method, the connecting member 30 is interposed between the gusset 10 and the brace 20 , and the gusset 10 and the brace 20 are joined via this connecting member 30 . Therefore, one end 31 of the connecting member 30 is shaped so that it can be attached to the first connection end 12 of the gusset 10 , and the other end 32 is shaped so that it can be attached to the second connection end 22 of the brace 20 . Even if the connecting end portion 12 and the second connecting end portion 22 have different shapes, they can be joined together. That is, even if the shapes of the existing gusset 10 and the brace 20 do not directly correspond to each other, there is no need to replace the existing gusset 10 according to the shape of the brace 20 on site as in the conventional art. Since the brace 20 can be used for reinforcement, the installation work can be greatly simplified, and the construction period can be shortened.
In addition, the shapes of the one end 31 and the other end 32 of the connecting member 30 may adopt shapes that are non-limitingly exemplified in some embodiments of the present disclosure.

In some embodiments, the other end 32 of the connecting member 30 and the second connecting end 22 may be joined with a fastening member 6 (eg, bolt/nut) in the mounting step S20 (see FIGS. 4-17). ). In this way, no unnecessary heat or axial force is applied to the brace 20 when joining the connecting member 30 and the brace 20 regardless of the method of joining the gusset 10 and the connecting member 30 . Therefore, it is possible to properly secure the function of the brace 20 after installation without generating unnecessary internal stress in the brace 20 mainly responsible for the damping function.

In some embodiments, in the attachment step S20, the first connecting end portion 12 and one end 31 of the connecting member 30 are joined with the fastening member 6, and the other end 32 of the connecting member 30 and the second connecting end portion 22 are connected. may be joined with a fastening member 6 (see, for example, FIGS. 4, 5, 8-12 and 15-17).
According to the above method, the connecting member 30 and both the gusset 10 and the brace 20 can be joined together by the fastening member 6 . Therefore, there is no need to perform a welding operation that may require a great deal of labor and time on site, and the joining operation between the gusset 10 and the brace 20 can be greatly simplified.

In some embodiments, in the attachment step S20, the first connecting end portion 12 and the one end 31 of the connecting member 30 are joined by welding, and the other end 32 of the connecting member 30 and the second connecting end portion 22 are fastened. It may be joined by a member 6 (see, for example, FIGS. 6-7 and 13-14).
According to the above method, the length of the connecting member 30 can be shortened by joining the gusset 10 and the connecting member 30 by welding. On the other hand, the brace 20, which mainly exerts vibration damping performance, is not subjected to welding heat or axial force, so that the function of the brace 20 after installation can be properly secured.

As illustrated in FIGS. 3(b), 10 and 13-14, in some embodiments, the first connecting end 12 comprises a first flange 13 and a second flange 13 arranged parallel to each other. 14 and a web portion 15 connecting the first flange portion 13 and the second flange portion 14, and cutting out at least part of the end portion 12 of the web portion 15 facing the connecting member 30 in step S5. may further include

According to the above method, at least a portion of the end portion 12 facing the connecting member 30 of the web portion 15 between the first flange portion 13 and the second flange portion 14 is cut away, and the cut gusset is formed. By joining the connecting member 30 to the brace 10, a long length of the brace 20 can be ensured. Therefore, when an axial force acts on the brace 20, the axial strain of the brace 20 is reduced, and the fatigue performance against repeated strain during an earthquake can be improved.

In some embodiments, the notching step S5 notches the first flange portion 13 and the second flange portion 14 in addition to the web portion 15, and the attaching step S20 notches the first flange portion 13 of the first connecting end portion 12. , the one end 31 of the connecting member 30 may be joined to the gusset 10 with the second flange portion 14 and the web portion 15 notched (see, eg, FIGS. 19-20).
According to the above method, by notching the first flange portion 13 and the second flange portion 14 in addition to the web portion 15, the gusset 10 can be made wider or more shaped at the joint with the one end 31 of the connecting member 30. Dimensions can be shortened while reducing constraints. Therefore, the length of the brace 20 attached to the other end 32 side of the connecting member 30 is secured while the degree of freedom in the shape of the one end 31 of the connecting member 30 that can be attached to the gusset 10 is improved, thereby reducing the axial strain. It is possible to improve the fatigue performance against repeated strain during earthquakes.

In some embodiments, the brace 20 may be a damping brace 20A (see, eg, FIGS. 1 and 2). The vibration control brace 20A may be, for example, a steel-based hysteresis damper, a high-damping rubber-based viscoelastic damper, a fluid-based viscous damper, or a brace with a damper.
According to the above method, the connecting member 30 is interposed between the gusset 10 and the vibration damping brace 20A (brace 20) in the interposing step S10, and the vibration damping brace is attached to the gusset 10 via the connecting member 30 in the mounting step S20. 20A is attached. That is, the damping brace 20A capable of efficiently absorbing seismic energy acting in the axial direction of the brace 20 when an earthquake occurs can be attached to the gusset 10 by a simpler method than before. Furthermore, as disclosed in the above several embodiments, if a part of the gusset 10 to which the brace 20 is attached is notched before the vibration control brace 20A is attached, the vibration control brace 20A responsible for the vibration control performance By ensuring a long length, the axial strain can be reduced, and the vibration control function of the vibration control brace 20A can be preferably exhibited.

In some embodiments, at least one end 31 of the connecting member 30 includes two flange portions 33 and 34 arranged parallel to each other and a web portion 35 connecting the two flange portions 33 and 34 to provide a connection. At least the other end 32 of the member 30 may include extending portions 35A and 36A extending in four directions perpendicular to the longitudinal direction X of the brace 20 (see FIG. 4, for example).
According to the above method, at least one end 31 of the connecting member 30 can be suitably joined with the gusset 10 having a shape including two flange portions 33 , 34 and the web portion 15 . On the other hand, at least the other end 32 of the connecting member 30 can be preferably joined to the brace 20 having a shape including extending portions 35A and 36A extending in four directions orthogonal to the longitudinal direction X.

In some embodiments, at least a portion of the connecting member 30 includes first and second planar flanges 33 and 33 arranged parallel to each other, for example, as shown in FIGS. A flange 34, a web 35 connecting the first flange 33 and the second flange 34, and an intermediate rib 38 erected on the web 35 parallel to the first flange 33 and the second flange 34 may be provided. .

In general, when connecting the brace 20 to the gusset 10 fixed to a column or beam, the brace 20 can be hung or lifted to perform the joining operation. Therefore, when joining the brace 20, it is desirable to reduce the weight of the brace 20 as much as possible.
In this regard, according to the method described above, the connecting member 30 is joined to the gusset 10 prior to being joined to the brace 20 . Therefore, compared to the case where the connecting member 30 is joined to the gusset 10 after the connecting member 30 is joined to the brace 20, the weight of the brace 20 side can be suppressed, so that the installation work of the brace 20 can be relatively easily performed. It can be carried out. Also, by joining the brace 20 and the coupling member 30 after joining the gusset 10 and the coupling member 30, additional stress is prevented from being applied to the brace 20, which mainly exhibits vibration damping performance. Therefore, it is possible to appropriately secure the function of the brace 20 after installation.
