VL Bracing Connection (Bearing Type) 2

VL Bracing Connection (Bearing Type)

A VL bracing connection refers to a specific type of connection used in structural engineering for bracing members. It is designed to provide resistance against lateral loads, such as wind or seismic forces, and is commonly used in steel structures.

The bearing type VL bracing connection relies on bearing stress transfer between the brace and the gusset plate. The brace, typically a steel section or a structural tube, is connected to a gusset plate that is welded or bolted to the main structural member.

Here’s a general description of the connection process:

Gusset plate preparation: The gusset plate is fabricated with holes or slots to accommodate the brace and the main member. It is typically thicker than the brace to provide sufficient strength and stiffness.

Brace connection: The brace is attached to the gusset plate. This can be done through welding or bolting, depending on the specific design requirements. Welding provides a continuous connection, while bolting allows for easier installation and potential disassembly.

Gusset plate connection: The gusset plate is then connected to the main structural member. This connection is typically achieved using bolts, which pass through the holes in the gusset plate and engage with the main member.

Load transfer: The load from lateral forces acting on the brace is transferred through the brace-to-gusset plate connection. The gusset plate, in turn, transfers the load to the main structural member through the gusset plate-to-main member connection.

The design of VL bracing connections takes into account factors such as the magnitude and direction of applied loads, material strength, bolt or weld capacities, and structural stiffness requirements. The connection must be designed to ensure that it can withstand the anticipated forces without failure.
