SkyCiv-Scherverbindungsrechner

The calculator sizes and checks a simple connection between steel members, the kind that delivers a beam end reaction into a column or a supporting beam. You choose the configuration, define the connecting element and the fasteners, then enter the design shear.

Es meldet einen Auslastungsgrad für jeden Grenzzustand und nicht nur ein einzelnes Bestehen oder Nichtbestehen, So können Sie sehen, welche Prüfung nahezu ausschlaggebend ist und was geändert werden muss, wenn dies nicht der Fall ist.

A shear connection transfers vertical shear from one member to another, typically from a beam into a column. It is a simple connection: it is detailed to carry the end reaction and to rotate at the joint, not to carry end moment.

That rotation is the point. A moment connection has to be stiff enough to hold the beam end against rotation, which takes heavier plates, more welding and often column stiffeners. A shear connection is allowed to rotate, so it stays light and quick to fabricate, which is why it is the default choice wherever the frame gets its lateral stability from somewhere else.

The components depend on the configuration, but they generally include:

• Platten: single or double plates bolted or welded to the beam and column.
• Winkel: single or double angles connecting the beam web to the support.
• End plates: plates welded to the beam end, then bolted to the column.
• Schrauben: fasteners securing the plates or angles to the members.
• Schweißnähte: used in place of bolts, most often on the supported side.
• Direct welds: joining the beam web straight to the column face.

Most configurations are welded on one side and bolted on the other. The weld is made in the shop, where access and position are controlled, and the bolts are left for the field, where the erector needs something quick to make and a little tolerance to work with.

Shear connections appear wherever a beam frames into a support and the frame gets its lateral resistance elsewhere, from bracing or a core. Zu den gängigen Anwendungen gehören::

• Rahmen für Gewerbe- und Wohngebäude.
• Industrieanlagen mit Stahlgerüsten.
• Brücken und Überführungen.
• Modulare Strukturen und vorgefertigte Designs.

They are the most numerous connection in a typical steel frame, which is why small savings in plate size or bolt count repeat across a job.

The calculator covers the configurations below, each suited to a different framing condition:

• Einzelplatte, also called a shear tab or fin plate: Eine Platte ist an die Stütze geschweißt und mit dem Trägersteg verschraubt. Usually the cheapest of the group, with one weld line and one bolt group.
• Double plate: plates either side of the web, where one plate cannot carry the reaction.
• Single or double angle: angles bolted or welded to the web and the support. A double angle puts the web fasteners in double shear.
• Endplatte: a plate welded across the beam end, then bolted to the column.
• Directly welded web: the beam web welded straight to the support, with no connecting element.

Picking between them is usually a fabrication question rather than a strength one. The reaction can be carried by any of them at the right size, so the choice comes down to access for the welder, what the erector can bolt up safely, and how much tolerance the fit-up needs.

Work through the inputs in this order:

1. Aufbau: pick single plate, Doppelplatte, single or double angle, Endplatte, or directly welded web.
2. Mitglieder: set the supported beam and the supporting column or beam, with their steel grades.
3. Connecting element: the plate or angle thickness, width and depth.
4. Vorrichtungen: Schraubenqualität, Durchmesser, Lochtyp und -anordnung, oder Schweißnahtgröße und Elektrodenstärke.
5. Bemessungslasten: the shear at the beam end, matched to the design method you selected.

Führen Sie dann die Designprüfungen durch. Match the load to the method: LRFD takes factored loads against design strength, ASD takes service loads against allowable strength, und der Rechner kann nicht erkennen, was Sie eingegeben haben.

If a check fails, the utilization ratio tells you which one and by how much. A plate limit state points at the plate thickness or depth; a bolt limit state points at the bolt count, diameter or edge distance.

Jede Formel, Die Designprüfung und die Codereferenz werden vollständig angezeigt, So kann die Arbeit Zeile für Zeile gelesen werden, anstatt aus einer Zahl rückentwickelt zu werden. That matters when the calculation has to be checked by someone who did not run it.

Außerdem führt es vor der Lösung die Detaillierungs- und Kollisionsprüfungen durch, which catch the connection that satisfies every strength calculation and still cannot be fabricated or erected. Bolts that cannot be reached with a wrench do not show up in a capacity equation.
