As shown in FIG. 8, a truss structure a which is a load-bearing wall is provided on a frame composed of a column member 1, a vertical beam 1 'and a horizontal beam 2. Are arranged so as to be shifted by a half span for each floor, and the load-bearing wall formed of the truss structure a has a staggered shape in a side view. The load-bearing wall is, for example, a truss structure using the diagonal members 3.

部材または柱材１の部材が大きくなり過ぎて建設コスト
がアップするという問題がある。However, in the above-mentioned staggered truss structure in the prior art,
When large-scale buildings such as warehouses and supermarkets are constructed, when the scale is increased, excessive bending moments are generated in the members at the ends of the truss structure a, which are load-bearing walls, and in the column capitals and column bases of the column 1. In order to prevent this, there is a problem that the members of the truss structure a or the columns 1 become too large and the construction cost increases.

ことが多い。[0009] Further, in the joint between a pillar and a pillar including other buildings in the prior art, when the transmitted load is large and the member size is increased, the number of bolts is increased,
The bending resistance cannot be ignored. In addition, since the axial force is transmitted, the entire body is required to be welded, so that it is often completely fixed.

Therefore, in the case of large-scale building structures, it is difficult to realize even if pillars are to be hinged.

ない。Further, since both ends of the upper floor or the lower floor of the cross beam constituting the truss structure which is the load-bearing wall are omitted, and can be attached to the column material by rotational joining or rigid connection, the end of the truss structure end can be provided. Since the constraint is reduced and a local bending moment is not generated in the column, there is no need to enlarge the column.

床面積を確保することができる。Further, since the floor material is made of a composite structure composed of the PCa plate and the reinforced concrete, it can withstand a large load, so that the interval of the truss structure can be made larger than before, and it can be used for a warehouse, a supermarket, etc. Suitable wide floor space can be secured.

要がない。Further, since the joints between the column members connected in the height direction are joints free of rotational displacement, a large bending moment is locally generated at the joint between the column members of the truss structure due to the rigidity of the column members. Therefore, there is no need to increase the size of the column member.
【００６１】さらに、コンクリート充填鋼管柱を柱材と

に有利となる。Further, when a concrete-filled steel pipe column is used as a column material, the local bending moment of the column material becomes small, so that the size of the column material can be made small, which is advantageous in cost.
