SkyCiv Vertical Bracing Connection Calculator

The calculator works on the connection between a diagonal brace, a beam and a column, made through a gusset plate. It checks tension and compression in the brace, en scheer, tension and compression in the beam, reporting each as a capacity and a utility ratio to AISC 360-16 bij ASS of LRFD.

Results follow from what you enter: the dimensions of the bracing member, the gusset plate properties, the steel material specifications, the bolt configuration and the applied design loads.

A vertical bracing connection is how a diagonal brace attaches to the frame it stabilizes. The brace resists lateral force from wind and seismic load, and the connection has to move that force into the beam and column without the joint becoming the weak point.

The attachment is usually made with a gusset plate and bolts. Getting it right is what keeps the frame rigid and limits the deformation it sees under lateral load.

Six parts make up a vertical bracing connection:

• Kolom: the vertical member supporting the framework.
• Straal: the horizontal member that resists bending.
• Beugel: the diagonal member providing lateral stability.
• Knoopplaat: the plate joining the brace to the beam and column.
• Bouten: the fasteners attaching the gusset plate to the members.
• Lassen: used to join members and plates where bolts are not applicable.

These work together to carry axial, shear and moment force across the joint.

Vertical bracing is used where a structure needs lateral stability:

• Hoogbouw.
• Industriële en magazijnframeworks.
• Bruggen en viaducten.
• Elektriciteitscentrales en zendmasten.
• Mechanische en offshore constructies.

The calculator suits any of these, since the checks depend on the members and plate you enter rather than the building type around them.

Moment-resisting frames and shear walls both resist lateral load without a diagonal brace, and either can be the right answer depending on the project.

Vertical bracing stays the primary solution for lateral load resistance, and it is preferred where simplicity, cost and ease of installation matter.

Enter the three members, the gusset plate, the fasteners and the design loads. The inputs are:

• Kolom: dimensions and material properties.
• Straal: dimensions and material properties.
• Beugel: dimensions and cross-sectional properties of the diagonal.
• Knoopplaat: dikte, width and material properties.
• Bouten: type, diameter and arrangement.
• Lassen: details of the welded connections, where there are any.
• Ontwerpbelastingen: tension and compression in the brace, plus shear, tension and compression in the beam.

Click calculate. The tool works out the utility ratios and capacities and produces a detailed report of the results to guide the design.

Each check comes back as a capacity next to a utility ratio, so an undersized gusset plate or bolt group is visible at a glance, and the report shows the working behind every number rather than a single pass or fail. The tool runs in the browser, so a bay can be checked without installing anything.

The full SkyCiv Connection Design module goes further: over 80+ pre-configured connection types, detailing and clash checks before the solve, CloudCAD detail drawings, and export of the 3D connection geometry directly to IFC.
