となり形状、おさまり等の経済性に問題があった。However, in general, the joints of beams in columns are subject to larger bending and shearing forces than other parts, so in steel pipe columns, it is necessary to make the wall thickness of this part thicker than other parts or to install a diaphragm. It is reinforced by The so-called outer diaphragm, which is provided in a ring shape on the outside of the steel pipe, has to have a large diaphragm that protrudes to the outside of the steel pipe in order to obtain sufficient strength, which poses problems in terms of shape, fit, etc., and economic efficiency.
また、内ダイヤプラムの鴨合には鋼管の内側て設置する
ことがなかなか困難である等の問題があった。In addition, there was a problem that it was difficult to install the inner diaphragm inside the steel pipe.
さらに鋼管内には梁材の接合部のみコンクリートを充填
補強すれば鋼管の全長に渡ってコンクリートを充填する
こともないのではないかと不経済についても問題とされ
ていた。Furthermore, there was also the problem of uneconomical filling of the steel pipes by filling only the joints of the beams with concrete, since it would not be necessary to fill the entire length of the steel pipes with concrete.
