However, in all of the connecting structures between the members shown in FIGS. 8 to 10, since the members are integrally connected by bolts and nuts, when an unexpected excessive load is received during a large earthquake or the like. In addition, there was a risk of fatal damage such as breakage of the connecting part, which would require a great deal of time, labor and cost to recover.

In particular, in the joint structure of the steel segment shown in FIGS. 9 (a) and 9 (b), bending and tensile stress are transmitted at the joint portion of the segment through the joint plates 37 and 37. Stress is concentrated on the plates 37 and 37, and the joint plates 37 and 37 may be easily deformed as shown in FIG. 8 (b), and there is a concern that the strength may be insufficient.

In a state where the fixing by the fixing means is released, the plurality of bearing portions of the connecting member on the first structural member side and the plurality of bearing portions of the connecting member on the second structural member side support each other. By making it possible to displace in the connecting direction of the first structural member and the second structural member within the region between the compression parts, it has the deformation ability and energy absorption capacity at the time of an earthquake, and is the largest scale within the conceivable range. In addition, it is possible to respond to an unexpected large earthquake that exceeds this range, and the bearing part has a stopper function to prevent unexpected displacement, which can be fatal such as collapse. Damage can be prevented.

Further, of the bearing portions of the connecting member on the first structural member side and the bearing portions of the connecting member on the second structural member side, which are alternately connected, at least one of the adjacent bearing portions is fixed. As a means, the strength of the connecting portion can be arbitrarily set by fixing with connecting bolts arranged in the connecting direction of the first structural member and the second structural member. Depending on the requirements of the connecting portion, the connecting portion may have a strength equal to or higher than that of the main body portion.
