量を増し、また加工工程を複雑にした。[Problems to be Solved by the Invention] Therefore, a large beam (2A) that receives a small beam (3) and a large beam (2A) that does not receive it
In B), the stress was different, and it was necessary to use members having different bulges and the like depending on the stress for each large flash. For this reason, it is necessary to provide at least three diaphragms (4) on each of the columns receiving the large flash, or to attach a haunch to the beam end. Further, since the large beam (2B) which does not receive the small beam has no constraint of the small beam, the bending buckling length becomes long and the allowable bending stress degree thereof decreases. In order to prevent it, it is necessary to shorten the bending buckling length,
It was necessary to provide a member (5) merely for bending buckling prevention. This increases the weight of steel used in steel structures and complicates the machining process.

無くすれば良い。[Means for Solving the Problems] In order to solve the above problems, the stress applied to the large beam should be the same in both the X and Y directions, and there is no member for merely bending buckling. Just do it.

小ばり（３）も曲げ座屈止めを兼ねることができる。First Embodiment FIG. 1 shows a first embodiment of the present invention. By arranging the small burrs (3) alternately in the X and Y directions, the load conditions that the large burrs (2) in the X and Y directions receive are the same, and therefore the stresses generated in the large burrs are also the same.
Further, since the small flash (3) also serves as a bending buckling stop for the large flash (2), a member only for bending buckling stop is not necessary, and the allowable bending stress degree of the large flash also decreases. There is no.
When the pillar spacing is wide, as shown in Fig. 2, a small beam (3)
The number should be increased so that the allowable stress level of (2) does not decrease. Similarly to FIG. 1, the stress generated in the large beam (2) can be the same in the X and Y directions, and the small beam (3) can also serve as a bending buckling stop.

By mounting the cross-shaped small burrs (3A), the large burrs (2) in the X and Y directions can be made the same member as in the first embodiment, and the small burrs (3A) can also be bent and buckled. Can be combined.
