A chevron brace connection (also known as a V-brace or inverted V-brace connection) occurs where two diagonal bracing members meet at a common intersection point along a horizontal beam. When one diagonal brace is under tension while the other experiences compression, significant vertical and horizontal force components transfer directly into the beam web and flange. Unlike single-diagonal framing, chevron bracing requires rigorous evaluation of beam bending and shear induced by unbalanced brace forces, particularly after brace buckling under seismic events.

The components that form a standard chevron brace connection include:

• Placa de refuerzo: The central structural plate that ties both diagonal bracing members to the main beam.
• Miembros de refuerzo: Diagonal structural shapes such as HSS sections, wide flanges, double angles, or channels.
• Beam Member: The supporting horizontal structural member that resists the combined vertical and shear forces transferred from the gusset plate.
• Pernos: High-strength fasteners used to connect the brace ends or lap plates to the gusset plate.
• Soldaduras: Fillet or groove welds securing the gusset plate directly to the beam flange or connecting HSS braces via slotted end connections.
• Refuerzos: Transverse beam web stiffeners added directly above or below the gusset connection to prevent web yielding or crippling.

These components must be collectively checked to ensure smooth force transfer without localized plate buckling or weld shear failure.

Chevron brace connections are widely used across diverse structural engineering framing systems, incluidos:

• High-rise and mid-rise commercial building frames requiring lateral drift control.
• Industrial steel structures, pipe racks, and heavy equipment support towers.
• Seismic-resistant braced frames (CBF and EBF systems) in active seismic zones.
• Openings in braced bays where door or window access is needed beneath the brace intersection.

Utilizing an AISC-compliant chevron brace connection calculator guarantees that all stability, sísmico, and strength requirements are met efficiently.

Chevron bracing configurations vary depending on geometry and fabrication preferences:

• Refuerzo en V invertida: Two braces meet at a point on the bottom flange of an overhead beam.
• Standard V-Bracing: Two braces meet at a point on the top flange of a lower beam member.
• Direct Welded Gusset Connection: The gusset plate is shop-welded directly to the beam flange with field-welded or field-bolted brace attachments.
• Bolted Lap / Splice Connection: Shear plates and lap splice plates are bolted directly to the gusset plate for quick site assembly.
• HSS Slotted Gusset Connection: Tubular brace ends are slotted and slipped over the gusset plate, secured with longitudinal fillet welds.

Each arrangement presents distinct failure modes—such as Whitmore section yield, corte de bloque, and gusset buckling—all of which are checked automatically by the software.

To design and check a chevron brace connection using the SkyCiv module, enter the following parameters:

• Configuración & Geometría: Select standard V or inverted V layout and input brace work-point angles and eccentricities.
• Member Profiles: Specify the beam section and brace profiles (p.ej., HSS, Forma de W, double angle).
• Gusset Dimensions: Input gusset plate thickness, la altura, anchura, y límite elástico del material ($F_y$).
• Fastener & Weld Details: Definir calidad de perno, diámetro, espaciado, distancias al borde, and weld sizes.
• Cargas de diseño: Enter tension and compression axial forces for each brace member.
