Connecting node for wide-flange H-section steel column added with horizontal draw bars on two sides and H-section steel beam

Abstract

The invention discloses a connecting node for a wide-flange H-section steel column added with horizontal draw bars on two sides and an H-section steel beam. The connecting node comprises the H-section steel column and the H-section steel beam, wherein the H-section steel column is provided with a column web plate and column flanges located on two sides of the column web plate, the H-section steel beam is provided with a beam web plate and beam flanges located on two sides of the beam web plate, the connecting end of the H-section steel beam is connected with an end plate, a plurality of horizontal draw bars are arranged in the length direction of the H-section steel column, the horizontal draw bars located in the middle penetrate through the column web flanges and the end plate and then are fixed through frictional high-strength bolts, and longitudinal draw bars are connected among the adjacent horizontal draw bars penetrating the end plate. By the adoption of the structure, local bending of the flanges of the H-section steel column is effectively prevented from being destroyed, the local stability of the section steel flanges is improved, and connection of the beam-column node is achieved on the premise that the strength of the H-section steel column is reduced to the greatest extent. In addition, the end plate is welded to the end of the section steel beam, so that the node for connecting the beam and the column has good stretchability, natural vibration period of the structure is prolonged, amplitude is decreased, and vibration damage is reduced.

Description

technical field [0001] The invention belongs to building structures, in particular to a beam-column connection node. Background technique [0002] In high-rise steel structures, when the thickness of the traditional H-shaped steel column flange is small, it is easy to cause the steel flange to protrude or indent under the load and cause buckling damage, which may lead to the bearing capacity and stability of the wide-flange H-shaped steel column. In order to ensure the local stability of the flange, the general idea is to increase the thickness of the flange plate, but this will increase the amount of steel and increase the construction cost, and the effect is not obvious. Contents of the invention [0003] Purpose of the invention: To provide a connection node between H-shaped steel columns and H-shaped steel beams with wide flanges on both sides and transverse tie rods, so as to solve the above-mentioned problems in the prior art. [0004] Technical solution: a connecti...
