Tube gusset (20)

Tube gusset (20)

Tube gusset (20) connects 1 to 10 hollow braces to a beam or a column using a gussetcomponent object that represents a plate that connects braces to a beam, column, or base plate

plate(1) part that represents a flat structure

(1) In some contexts, for example in analysis, the term plate object may be used to refer to plates.

(2) plate that represents a steel structure

(2) Plate is mainly used as a connection piece or as a floor plate.

. The braces need to have a rectangular hollow section (RHS) or a tube profile. The connection bolts the braces to the gusset plate using a connection plate and an optional tongue plate. The hollow braces can be sealed with end plates.

Objects created

  • Gusset plate

  • Connection plates

  • Clip angles

  • End plates (seal plates)

  • Tongue plates

  • Cover plates

  • Stiffeners

  • Bolts

  • Welds

Selection order

  1. Select the main part(1) part that exists in a building object and that determines the position number for the assembly or cast unit and the direction of assembly or cast unit drawings

    (1) Main part can be an assembly main part or a cast unit main part.

    (2) input part that the user selects first when creating a component

    (2) Connections and details always have a component main part.

    (column or beam).

  2. Select the secondary part(1) part that exists in a building object and that is connected to the main part

    (1) Secondary part can be an assembly secondary part or a cast unit secondary part.

    (2) input part that the user selects after selecting the component main part when creating a component

    (2) A component can have none, one or more component secondary parts.

    (first brace).

  3. Select the second secondary part (second brace).

  4. Select the subsequent secondary parts (subsequent braces).

  5. Click the middle mouse button to create the connection.
