Sheeting settings

The sheeting is completely defined by means of:

The settings for the diaphragm are:

Name

Name of sheeting settings set.

Sheeting Lib

Type of defined sheeting.
Position

+z: Means that the sheeting is placed on the positive side of the z-axis (LCS) of the member

-z: Means that the sheeting is placed on the negative side of the z-axis (LCS) of the member

k

The value of coefficient k depends on the number of sheetings:

k = 2 for 1 or 2 lateral spans,

k = 4 for 3 or more spans.

Sheeting position

The position of the sheeting may be either positive or negative.

Positive means that the sheeting is assembled in a way so that the width is greater at the top side.

Negative means that the sheeting is assembled in a way so that the width is greater at the bottom side.

Bolt position

Bolts may be located either at the top or bottom side of the sheeting.

Bold pitch

Bolts may be either:

in every rib (i.e. "br"),

in each second rib (i.e. "2 br").

Lf - Frame distance

The distance of frames (i.e. the span of transverse bonds).

ld - Sheeting length

The length of the transverse bond.

Geometry

Co-ordinate definition

Defines the co-ordinate system in which the position x is inputted.

Position x1

Value x1 specifies the begin-point of the sheeting on the beam.

Position x2

Value x1 specifies the end-point of the sheeting on the beam.

Origin

Defines the origin from which the position x is measured.
The procedure to apply the sheeting

  1. Open Sheetings input dialog:

    1. either via the process toolbar: Aluminium > Aluminium sheeting.

    2. or using the Input panel: Aluminium addtional data > Aluminium sheeting.

  1. Type required values and select appropriate options.

  2. Confirm with [OK].

  3. Select the member where the data are to be defined.

  4. End the function.
