The number of the first upper constraint ribs 51 and the number of the second upper constraint ribs 52 are respectively 2, and 2 first upper constraint ribs 51 are correspondingly arranged and respectively welded on two sides of the upper longitudinal stiffening rib 41; 2 second upper constraint ribs 52 are correspondingly arranged and respectively welded on two sides of the upper longitudinal stiffening rib 41; the number of the first lower constraint ribs 61 and the number of the second lower constraint ribs 62 are respectively 2, and 2 first lower constraint ribs 61 are correspondingly arranged and respectively welded on two sides of the lower longitudinal stiffening rib 42; the 2 second lower constraining ribs 62 are correspondingly disposed and welded to the two sides of the lower longitudinal stiffener 42, respectively.

The distance L between the first upper restraint rib 51 and the lower end of the upper longitudinal stiffener 411The distance between the first upper restriction rib 51 and the second upper restriction rib 52 is L2The distance L between the second upper constraining rib 52 and the upper end of the upper longitudinal stiffener 413，L1﹤L2﹤L3(ii) a The distance L between the first lower constraining rib 61 and the upper end of the lower longitudinal stiffener 421' and the distance between the first lower restriction rib 61 and the second lower restriction rib 62 is L2' and the distance between the second lower constraining rib 62 and the lower end of the lower longitudinal stiffener 42 is L3′，L1′﹤L2′﹤L3′。
In the 3-segment stress zone of the upper longitudinal stiffening rib 41, a main stress segment is arranged between the first upper restraining rib 51 and the lower end of the upper longitudinal stiffening rib 41, the segment is short in length and not easy to distort and deform, and the first upper restraining rib 51 can better restrain the buckling deformation of the upper longitudinal stiffening rib 41 at the segment; between the first upper constraint rib 51 and the second upper constraint rib 52, that is, the middle section of the upper longitudinal stiffening rib 41 is a secondary stressed section, the length of the secondary stressed section is longer than that of the primary stressed section, and the impact of the force left after the buckling of the primary stressed section can be buffered within a longer distance; the second upper constraint rib 52 and the upper end of the upper longitudinal stiffening rib 41 are stressed the least, the length of the segment is the longest, and the impact after the buckling of the main stressed segment and the secondary stressed segment can be completely absorbed within the longest distance. The first upper constraining rib 51 and the second upper constraining rib 52 divide the upper longitudinal stiffener 41 into three force bearing zones of different distances, which can increase the load bearing capacity of the upper longitudinal stiffener 41 to a greater extent.
Similarly, the first lower constraining rib 61 and the second lower constraining rib 62 divide the lower longitudinal stiffener 42 into three force-bearing zones of different distances, which can increase the load-bearing capacity of the lower longitudinal stiffener 42 to a greater extent.
First upper constraining rib 51 has a thickness greater than the thickness of second upper constraining rib 52 and first lower constraining rib 61 has a thickness greater than the thickness of second lower constraining rib 62.
With this structure, the rigidity of the first upper and lower constraining ribs 51 and 61 is made greater than the rigidity of the second upper and lower constraining ribs 52 and 62.
Since the upper longitudinal stiffener 41 between the first upper constraining rib 51 and the lower end of the upper longitudinal stiffener 41 is the primary stressed section, the upper longitudinal stiffener 41 between the first upper constraining rib 51 and the second upper constraining rib 52 is the secondary stressed section; the lower longitudinal stiffener 42 between the first lower restraint rib 61 and the upper end of the lower longitudinal stiffener 42 is a primary stressed section, and the lower longitudinal stiffener 42 between the first lower restraint rib 61 and the second lower restraint rib 62 is a secondary stressed section, so that the first upper restraint rib 51 and the first lower restraint rib 61 are rigid and less prone to deformation, and the upper longitudinal stiffener 41 and the lower longitudinal stiffener 42 can be restrained well.
The first upper restraint rib 51 has an area greater than that of the second upper restraint rib 52, and the first lower restraint rib 61 has an area greater than that of the second lower restraint rib 62.
Since the upper longitudinal stiffener 41 between the first upper constraining rib 51 and the lower end of the upper longitudinal stiffener 41 is the primary stressed section, the upper longitudinal stiffener 41 between the first upper constraining rib 51 and the second upper constraining rib 52 is the secondary stressed section; the lower longitudinal stiffener 42 between the first lower restraint rib 61 and the upper end of the lower longitudinal stiffener 42 is a primary stressed section, and the lower longitudinal stiffener 42 between the first lower restraint rib 61 and the second lower restraint rib 62 is a secondary stressed section, so that the first upper restraint rib 51 and the first lower restraint rib 61 are rigid and less prone to deformation, and the upper longitudinal stiffener 41 and the lower longitudinal stiffener 42 can be restrained well. Therefore, the first upper and lower constraining ribs 51 and 61 have a large area, are high in rigidity, are not easily deformed, and can constrain the upper and lower longitudinal stiffeners 41 and 42 well.
The distance between the upper longitudinal stiffening rib 41 and the left side surface of the upper angle steel 31 is equal to the distance between the upper longitudinal stiffening rib 41 and the right side surface of the upper angle steel 31, and the distance between the lower longitudinal stiffening rib 42 and the left side surface of the lower angle steel 32 is equal to the distance between the lower longitudinal stiffening rib 42 and the right side surface of the lower angle steel 32. The upper longitudinal stiffener 41 is welded to the centerline of the upper angle steel 31, and the lower longitudinal stiffener 42 is welded to the centerline of the lower angle steel 32. By adopting the structure, the upper longitudinal stiffening rib 41 and the upper angle steel 31 as well as the lower longitudinal stiffening rib 42 and the lower angle steel 32 are structurally symmetrical and are balanced in stress, the reciprocating load action born at the node of the beam column can be buffered by buckling of the upper longitudinal stiffening rib 41 and the lower longitudinal stiffening rib 42, the beam column steel frame is not easy to twist and generates larger residual deformation, and the structural deformation of the steel frame is smaller.
