The structural steel frame is a comprehensive grid system
connected by beams and beams, including the walls, flooring and roofs
of the building. Liang and beams are usually made of structural
steel. This material is known for its excellent strength and
ductility. According to the design load of the building, different
types of structural steel frameworks are used when building some
parts of the building or building.
Skeleton
Steel Frames Typically used for multi-story buildings, skeleton steel frames
support a building’s walls and floors by channeling the weight of
the structure into the foundation. Beams and girders are connected by
a variety of components, including brackets, haunches, gusset plates,
and shims. Spandrel beams are often installed around the perimeter of
skeleton steel frames to support masonry walls.
Wall-Bearing Frames
Ideal for single-story and other low structures, wall-bearing frames
allow interior and exterior walls to support the floor and roof
loads. They are typically attached to the main structure via anchor
bolts and end steel plates. The use of wall-bearing frames depends on
the shorter distance between supports and the load intensity of the
structure.
Long-Span Frames
For large buildings with wide spans between the beams and girders,
long-span frames are used. Common examples of these types of
structures are arenas, theaters, auditoriums, and large industrial
buildings. These structures often have heavier load-bearing
requirements, which are supported by long-span frames. Long-span
frames can be used as:
Trusses – Ultra rigid against bending, trusses can span longer
distances than single beams.
Girders – Thicker than traditional structural steel beams, girders
provide the necessary strength to bear heavy loads across wider
distances.
Rigid frames – Designed as a continuous system, rigid frames are
strong enough to withstand intense shear forces.
