Abstract

The invention discloses a split connection node in the minor axis direction of a PEC (partially encased composite) column and a construction method thereof. The split connection node comprises the PEC(partially encased composite) column, a node domain tie bar, a stressed-skin diaphragm and a beam, one end of the node domain tie bar is fixed on an upper flange of the PEC (partially encased composite) column, the other end of the node domain tie bar is fixed on a lower flange of the PEC (partially encased composite) column, the side surface of the stressed-skin diaphragm is fixed on the end surface of the upper flange and the end surface of the lower flange in the PEC (partially encased composite) column, a PBL shear part is fixed on the side surface of the stressed-skin diaphragm and is provided with a first through hole for allowing the node domain tie bar to penetrate through and a second through hole for allowing a short steel bar to penetrate through, the beam is fixed on the stressed-skin diaphragm, and concrete is poured in a space defined by a web plate, the upper flange and the lower flange of the PEC (partially encased composite) column and the stressed-skin diaphragm. According to the node, the problem that the stressed-skin diaphragm is prone to become warped after being stressed can be effectively avoided, the design concept of a strong node and a weak component ismet, and the construction is relatively convenient.

Description

technical field [0001] The invention belongs to the technical field of steel structures, and relates to a segmented connection node in the weak axis direction of a PEC column and a construction method thereof. Background technique [0002] The existing PEC column is a concrete surface in the direction of the weak axis, which is not convenient for connecting beams and other structural components. If a skin slab is added in the direction of the weak axis of the PEC column to connect the beam, the skin slab is prone to buckling after being stressed, that is, the separation of the slab and the concrete is not conducive to the joint force, and there is also a backlash "strong node, weak member" design ideas. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a segmented connection node in the direction of the weak axis of the PEC column and its construction method, which can effe...
