Description

H-shape Beam-Column Connection Detail using H-shape Stiffener in Weak Axis of H-shape Column

The present invention relates to the weak axis joint structure of H-beam column-beam, and the horizontal stiffener is installed on the web of the column to prevent local buckling in the web of the column by the bending moment acting on the beam joined to the weak axis of the column. It also relates to the weak shaft joint structure of H-beam column-beam using H-shaped stiffener which has excellent joining strength and ductility while having reasonable joining details without unnecessary joining elements.

The steel structure is a furniture structure that joins the parts processed and manufactured at the factory to factories and construction sites. Steel structures are used not only for high-rise buildings but also for mid- and low-rise buildings with various economic benefits such as shortening of construction period, reduction of construction cost, and ease of construction. The tendency to do so is increasing. Therefore, in the middle and low-rise buildings, it is very important to develop the column-beam joints in detail for the spread of steel structures.

Column-beam joints can be divided into a coaxial joint for joining the beam to the pillar's axial direction, that is, the flange of the column, and a weak contract joint for joining the beam to the web of the column, that is, the beam's weak axis direction. Although many researches and developments have been made on the rigid joints, few studies have been conducted on the weak joints.

Figure 4 shows the H-beam column-beam weak axis joint structure using a bracket-type weld joint, which is the most commonly used column-beam weak axis joint method.

As shown in the figure, the bracket-type welding method uses the H-shaped steel 70 of a predetermined length having the same cross-sectional shape as the H-beam 30 and the flanges 12, 12 'and the web ( 14) to make a joining bracket by welding a high-strength bolt to the bracket using the H-beam 30 to the joint plate (80). In addition, in order to suppress local deformation and buckling in the panel zone of the H-beam column 10, a horizontal stiffener 90 is provided between both flanges 12 and 12 'of the H-beam column 10.

However, this bracket-type welding method has a large amount of welding, which causes brittle behavior of the joint and tends to be over-designed. The horizontal stiffener not only acts as a factor preventing the construction of weak contraction in the field, but also the welding bracket is welded to the column. There is a problem that the transport is limited to transport.

The present invention was devised in view of the problems of the above-described pillar-beam weak axis joining method, and there is no need to install a horizontal stiffener separately, and it is possible to maintain excellent strength and ductility while having fewer welding points. It is an object to provide a weak shaft joint structure of an H-beam column-beam.
