た。2. Description of the Related Art Various types of joint structures have been proposed for the projecting method of an H-shaped steel beam from an RC column. However, if the H-shaped steel beam is simply crossed in order to emphasize stress transmission in a panel zone, concrete is not required. There was a contradiction that if the fillability of the panel zone was poor and the amount of metal in the panel zone was small, stress transmission would be questioned.

In addition, there is a problem that the filling property of the concrete and that when a stress is applied to the plate in the x direction, the plate in the y direction is twisted.

The shaped steel beams are connected to each other, and the reinforcing plate forms a stepped cross.

In FIG. 2, reference numeral 5 denotes an L-shaped steel as a connecting member surrounding the four sides, and a horizontal frame of the L-shaped steel is formed to face the inside of the four sides to form a four-sided frame. The vertical plane of the L-shaped steel is inscribed in the column main reinforcement 6, and the horizontal plane is the H-shaped steel beam B in four directions.
It is welded to the end flanges 1 of Ba, C, and Ca to be integrated and buried in the RC column.
【０００８】四方枠の平行する２辺のＬ型鋼５は同じ方
向の縦補強プレート３と相乗してＲＣ柱を介して連続す
る２つのＨ型鋼梁Ｂ、Ｂａの応力の伝達が行われる。The L-shaped steel members 5 on two parallel sides of the four-sided frame synergize with the vertical reinforcing plate 3 in the same direction to transmit the stress of two continuous H-shaped steel beams B and Ba via RC columns.

３と３ａで縦補強プレートの段違い十文字を形成する。The connection of the H-shaped steel beams C and Ca to each other in the panel zone is performed by connecting the end plates 4 and 4a fixed to the ends of the H-shaped steel beams with the longitudinal reinforcing plates 3a connected to face each other.
In the x direction, the vertical reinforcing plate connecting the opposing 5, 5a of the L-shaped rope of the four-sided frame at the upper and lower levels as 3,
3 and 3a form a cross in the vertical reinforcing plate.

断抵抗が増大し、パネルゾーンの剛性が高まる。Since the X-direction longitudinal reinforcing plate 3 connects the L-shaped steel members 5, 5a fixed above and below the flange 1 of the H-shaped steel beam, the panel zone becomes larger than the beam, and the shear resistance increases. The rigidity of the panel zone increases.
【００１１】段違い縦十文字補強プレートのため、ｘ方
