FREE COLUMN SPLICE CONNECTION CALCULATOR

SkyCiv Kolomlasverbindingscalculator

This column splice connection calculator checks the bolted flange plates and web plates joining two W-shaped columns, and returns the capacity and utility ratio for strong-axis moment, spanning, compression and strong-axis shear. The checks follow AISC 360-16, bij ASS of LRFD.

Columns in multi-story frames are spliced because a single length cannot be fabricated, transported and handled in one piece. The splice has to pass load and moment from the column above into the column below as though the member were continuous.

Over de rekenmachine voor kolomsplitsingsverbindingen

The calculator works on splices between W-shaped columns joined by bolted flange plates and web plates. It evaluates strong-axis moment, spanning, compression and strong-axis shear from the properties of the columns and plates you enter, reporting each as a capacity and a utility ratio.

Controles volgen AISC 360-16 bij ASS of LRFD, and the output includes the calculations behind the numbers rather than a bare pass or fail.

Wat is een kolomsplitsingsverbinding?

A column splice joins two vertical members, usually W-shaped columns, om hun lengte te verlengen. Flange plates and web plates are bolted across the joint so the two segments behave as one member.

Splices are what let columns in high-rise construction be fabricated and transported in lengths that can actually be handled. The connection carries axial force, moment and shear, so the frame above is supported as though the column ran uninterrupted.

What Components Make Up a Column Splice?

Four parts make up the connection:

  • W-shaped columns: the vertical members supporting the structure.
  • Flange plates: bolted to the column flanges to transfer bending moment.
  • Web plates: bolted to the column webs to resist shear.
  • Bouten: the fasteners holding the flange and web plates in place.

Together they move load and moment across the splice and keep the two column segments continuous.

Where are Column Splices Commonly Used?

Column splices appear wherever a column runs taller than one fabricated length:

  • High-rise buildings needing column extensions.
  • Industriële structuren met raamwerken met meerdere verdiepingen.
  • Bridge piers and other infrastructure.
  • Torens en hoge mechanische constructies.

The calculator suits all of these, because the checks depend on the columns, plates and loads you enter rather than the structure around them.

What Are the Benefits of a Column Splice?

  • Transport and handling: columns can be fabricated in shorter sections that are easier to move and lift.
  • Structural continuity: load transfers between segments, so the spliced column acts as one member.
  • Range of actions: the same detail can be designed for moment, spanning, compression and shear.
  • Code checks: capacities follow AISC 360-16, bij ASS of LRFD.

Hoe u de kolomlasverbindingscalculator gebruikt

Enter the columns, the plates, the bolts and the design actions at the splice. The inputs are:

  • W-shaped column properties: dimensions and material properties of the connected columns.
  • Flange plate details: dikte, width and material properties.
  • Web plate details: dikte, height and material properties.
  • Bolt specifications: type, diameter and arrangement.
  • Ontwerpbelastingen: strong-axis moment, spanning, compression and strong-axis shear.

Click calculate. The tool evaluates the utility ratios and capacities and generates a detailed report to keep with the design.

Why Choose SkyCiv for Column Splice Design?

Each check is reported as a capacity next to a utility ratio, so an overloaded plate or bolt group is obvious without reading the whole report, and the workings are shown rather than hidden. It runs in the browser, so a splice can be sized without installing anything.

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

What does the column splice connection calculator check?

It evaluates strong-axis moment, spanning, compression and strong-axis shear at the splice, returning a capacity and a utility ratio for each.

Dimensions and material properties for the two columns, the flange plate thickness, width and material, the web plate thickness, height and material, the bolt type, diameter and arrangement, en het ontwerp laadt.

AISC 360-16, in ASS of LRFD. Pick the method the project works to and the capacities and utility ratios follow it.

W-shaped columns. The detail relies on flange plates bolted to the flanges and web plates bolted to the webs, so the section needs both.

Because a column taller than one fabricated length cannot be transported or handled in one piece. Splicing lets it be made in shorter sections and joined on site.

The design action divided by the capacity for that check. At or below 1.0 the component passes; bovenstaande 1.0 it is overloaded and the plate, bolt group or column has to change.

Ja. Sterk-asmoment, spanning, compression and strong-axis shear are all inputs, and the calculator reports a capacity and a utility ratio for each.

Ja. Alongside the utility ratios and capacities it generates a detailed report, so the calculations can go into the design file.
