Box Girders

The steel structure building is composed of the main frame connected by H-beam,
C-purlin and Z-purlin steel components. Roofs and walls use various panels as
well as other components such as doors and windows. Steel structure buildings
have the advantages of large span, high strength, light weight, low cost,
temperature resistance, energy saving, beautiful appearance, short construction
period, good thermal insulation effect, long service life, space saving, good
seismic performance, and flexibility.

Description of steel box girders
Box girders are convenient structural members for flexurally resistant frames,
but due to the closed shape of box columns and the difficulty of accessing
internal columns to create a reliable load path, providing proper beam-to-box
column connections is still under investigation. To solve this problem, a new
easy-to-manufacture moment connection is proposed for connecting I-beams to box
columns. The connection consists of vertical plates that pass through the
columns and are welded to the column flanges, and beams that are connected to
plates called through plates.

Advantages of Box Girders

1. High strength

2. Light

3. Material is uniform

4. Good ductility

5. Easy installation

6.Short construction period

Structure of Box Girders

Steel box girder structure Steel beam and column welding Box steel column
consists of 4 steel plates. Four - way fillet welds are divided into full -
penetration groove and partial weld groove according to strength. The box
column is provided with a horizontal partition board and a main diaphragm
board. The welding adopts the web nozzle electroslag welding, the box body is
welded on three sides between the ordinary diaphragm and the cover plate, and
the secondary beam of the main beam is vertically supported by the leg and the
eye plate on the outside of the special-shaped column. The connection between
the column and the column is a combination of welding and top fastening.
