Sheeting definition

Name

Name of the sheeting.

I moment

Moment of inertia (i.e. second moment of area) per length.

K1 +

Factor K1 for positive position.

K2 +

Factor K2 for positive position.

K1 -

Factor K1 for negative position.

K2 -

Factor K2 for negative position.

Geometry

A

Dimension A: see the Fig. below.

B

Dimension B: see the Fig. below.

C

Dimension C: see the Fig. below.

D

Dimension D: see the Fig. below.

Thickness

Thickness of the sheet.

Nominal thickness

"Nominal thickness" is the "gauge value" whereas "Thickness" is the "actual thickness" of the profile deck. This value is used ONLY for Composite beam design checks. It is not used in normal steel design checks.

The dialogue for the definition of a sheeting is the same for both steel and aluminium structures, thus the value is present here as well. It has no practical meaning for aluminium structures.

The procedure for definition of a new sheeting

  1. Open the database manager for sheetings:

    1. either using tree menu function Library > Sheetings,

    2. or using menu function Libraries > Sheetings.

  2. Click button [New] to create a new sheeting.

  3. A new sheeting is added into the list of defined sheetings.

  4. Click button [Edit] to edit its properties.

  5. Input the parameters.

  6. Confirm with [OK].

  7. Close the database manager.

Note: A new sheeting is defined in the program tool called Database manager. The database manager can be used not only for the definition of a new sheeting, but also for editing of existing ones, for removal of no more necessary ones, and for other operations related to the management of sheeting database.

In addition, other settings must be made in order to apply the sheeting in a structure model.
