Abstract

The invention discloses a rigid-connection node of a combined steel-pipe concrete column and a steel beam. The rigid-connection node comprises the combined steel-pipe concrete column and the steel beam, wherein the combined steel-pipe concrete column comprises two H-shaped section steels which are vertically distributed and are welded into a whole body; the web plates of the section steels are provided with anti-shearing bolt pins along the height direction; concrete is cast in a cavity enclosed by the two section steels, and the concrete and the section steels are connected into a whole body by the anti-shearing bolt pins; the combined steel-pipe concrete column is provided with side plates vertically distributed; the steel beam is distributed between the two side plates; a horizontal connecting plate extends on a flange of the steel beam adjacent to the end of the combined steel-pipe concrete column towards the direction of the side plates; the steel beam is welded with the side plates by the horizontal connecting plate; and the web plates of the steel beam are welded with the combined steel-pipe concrete column by using double-sided angle welding seams. The rigid-connection node disclosed by the invention has the advantage that since the width of a flange is increased by the horizontal connecting plate at a node area through the steel beam, the design criterion of strong nodes and weak members is realized.

Description

technical field [0001] The invention belongs to the technical field of building structure engineering, and in particular relates to a rigid connection node of a composite steel pipe concrete column and a steel beam. Background technique [0002] At present, the connection of steel beams and steel columns, especially steel tube concrete columns, often adopts the method of internal partitions. The internal force of the steel beam is transmitted to the CFST through the internal diaphragm of the column. The main disadvantage of this method is that it is difficult to manufacture the inner partition, and it affects the pouring and strength of the concrete in the pipe, which brings hidden dangers to the project. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a rigid connection joint between a composite steel pipe concrete column and a steel beam. This joint adopts the method that the steel beam flange transmits ...
