Ořez prutu

Objekty ve spoji lze upravovat několika způsoby. Jedním z nich je komponenta Ořez prutu. Umožňuje upravit konec prutu v oblasti spoje. Existují tři způsoby střihu na základě referenčního objektu pro řez: cutting by member, by auxiliary plane, and by plate.

To Cut

In the first category of the "Component Settings" area, you can define the member to be cut followed by the type of cut. As stated above, the types are by member, by auxiliary plane, and by plate. Podrobný popis každého typu řezu najdete níže. Poslední řádek určuje referenční objekt, který je rozhodující pro proces úpravy.

Nastavení pro řez

Detaily pro zadání této kategorie závisí na zvoleném typu řezu.

By Member

The cut type by member is used when a member (Cut via) determines the space of another member (Member to cut) that needs to be modified due to potential collision.

The first line in the "Cut Settings" category controls the Cutting method. The first of the available methods is the Plane option which guides the cut by the closest plane of the bounding box of the reference member. Druhou metodou je volba Plocha. It only cuts off the intersection parts of cross-sections.

The Bounding box and Convex hull options are particularly suitable when creating intersections for asymmetrical cross-sections.

When cutting by plane, you can select which Cutting plane is the controlling one, that means whether it is Closer or Farther from the connected member side. The default status is Closer, as it is the more common case. Níže uvádíme několik příkladů obou možností řezu. In the first image, you can see members with no cut applied. In the middle image, the beam is cut via the column with the Cutting plane option set to Closer. In the last image, a new member cut was added with the column being cut via the beam, with the Cutting plane option set to Farther.

The last setting, which is specific to cutting by plane, is the Direction of the cut. Máme přitom dvě možnosti: Paralelně nebo Kolmo. Paralelně znamená, že rovina řezu je rovnoběžná s vztažným prutem (Řez pomocí). The Perpendicular direction means that the cutting plane is perpendicular to the connected member axis at the closest point of contact of both members.

For both cutting methods—Plane and Surface—it is also possible to set an Offset of the cut, in which the actual cutting takes place. Přípustné jsou kladné i záporné hodnoty.

By Auxiliary Plane

Místo existujícího prutu lze jako referenční objekt použít pomocnou rovinu. In that case, the additional settings consist of the Direction of the cut and the Offset, similarly to cutting by member. The options for the Direction are the same, Parallel to the auxiliary plane or Perpendicular to the connected member axis at the closest point of contact of the member and the auxiliary plane (the member alignment is taken into account – see the info box above).

By Plate

The By plate type of cut is similar to cutting by auxiliary plane. The main difference is that, while the auxiliary plane has no thickness, the plate does. Therefore, it is possible to choose the cutting method either by Plane or by Surface. Apart from the cutting method, the additional settings are Direction and Offset, as described above.

Svary

V případech, kdy střih vytváří kontakt mezi deskami nebo deskami prutu, je možné definovat svar. For each contact of a plate edge and a plate face, a new weld definition line appears in the Welds category of the "Component Settings" area. The definition contains a check box that controls whether the weld is to be used, a weld type box, and for the fillet weld option, the option to define the weld thickness.
