Due to the large thickness and high rigidity, the upper and lower transverse restraining ribs can effectively restrain the deformation of the upper longitudinal stiffening rib 41 and the lower longitudinal stiffening rib 42. It is divided into upper and lower stress areas, so that the upper longitudinal stiffener 41 and the lower longitudinal stiffener 42 are transformed from the single-segment large buckling of the single-segment stress area to the segmental buckling of the two-segment stress area during the bearing process. segmented power consumption.

The length of this section is short and is not easily deformed. The restraining rib 51 can better restrain the buckling deformation of the upper longitudinal stiffening rib 41 in this section; between the first upper restraining rib 51 and the second upper restraining rib 52, that is, the middle section of the upper longitudinal stiffening rib 41 is the secondary stress section, The length of this section is longer than that of the main stress section, which can buffer the force impact left after the buckling of the main stress section in a long distance; the force between the second upper restraining rib 52 and the upper end of the upper longitudinal stiffening rib 41 is the smallest, and the length of this section is the smallest. The longest, which can completely absorb the impact after the buckling of the main and secondary force sections within the longest distance. The first upper restraining rib 51 and the second upper restraining rib 52 divide the upper longitudinal stiffening rib 41 into three sections of stress areas with different distances, which can increase the bearing capacity of the upper longitudinal stiffening rib 41 to a greater extent.

The upper longitudinal stiffening rib 41 is welded to the centerline position of the upper angle steel 31 , and the lower longitudinal stiffening rib 42 is welded to the centerline position of the lower angle steel 32 . This structure makes the upper longitudinal stiffener 41 and the upper angle steel 31 and the lower longitudinal stiffener 42 and the lower angle steel 32 symmetrical in structure, the force is balanced, and the reciprocating load at the beam-column joint can pass through the upper longitudinal stiffener 41 and the lower longitudinal stiffener 41.

在染柱节点处承担往复荷载作用时,上角钢31和下角钢32受力变形会使与之连接的钢柱1发生变形,由于第一柱内横向加劲肋71与上角钢31对应设置,第二柱内横向加劲肋72与下角钢32对应设置,第一柱内横向加劲肋71和第二柱内横向加劲肋72能够抵抗钢柱1的变形,使钢框架不会产生较大的残余变形。第一柱内横向加劲肋71与上角钢31以及第二柱内横向加劲肋72与下角钢32均分别设置在钢柱1两侧,从钢柱1两侧对钢柱1形成夹持,提高了钢框架的稳定性和抗扭性能。When the node of the dye column bears the reciprocating load, the upper angle steel 31 and the lower angle steel 32 are deformed by force, which will cause the steel column 1 connected to it to deform. The inner transverse stiffeners 72 of the second column are arranged corresponding to the lower angle steel 32. The inner transverse stiffeners 71 of the first column and the inner transverse stiffeners 72 of the second column can resist the deformation of the steel column 1, so that the steel frame will not produce large residual deformation. .
