Stiffener Distribution - Layout tab

Used to define different parameters of stiffeners being distributed, in terms of number of stiffeners, type, their layout and dimensions. These parameters alter the stiffener’s appearance or where they are inserted relative to the support shape.

SettingDescription
Uniform Layout When checked, each stiffener will have same parameters.
Stiffener Number Selects the desired stiffener number from the list to set different parameters.
Layout Sets the shape of the inner corners of the stiffeners; one from the available options:
  • Chamfer
  • Filled, or
  • Rounded.
Length Sets the length of the stiffeners, based inner edge form selected from the drop-down list;
  • Full Stiffener – The stiffener height extends over the complete web height of the shape.
  • Half Stiffener – The stiffener height stretches over half the web height of the shape where the side is determined by the picked side.
  • By Length – The stiffener is given the height specified by you. Only values between 10-90% of the web height can be used.
  • Edge – The height of the stiffener is determined according to the specifications, but the layout is a triangle shape.
Flip icon Flips the stiffener length.
Dimensions
  1. Thickness – Sets the thickness of the stiffener plate; this value is taken from the table or it can be entered freely if this setting has been activated.
  2. Flange Offset – When calculating the stiffener dimensions, this is the distance to the flange side, i.e., the stiffener height is slightly reduced.
  3. Web Distance – When calculating the stiffener dimensions, this is the distance to the web side, i.e., the stiffener width is slightly reduced.
  4. Length – This is the value for the stiffener length when you have selected the stiffener length ‘To Measure’.
  5. End Offset – When calculating the stiffener dimensions, this is the distance to the outer edge of the flanges, i.e., the stiffener width is slightly reduced. If the stiffener is to slightly project towards the outside, type a negative value.
  6. Round to – The Round to value describes a rounding accuracy applicable to the width of the calculated stiffened plate. Rounding is carried out after calculation of the projection.

    Using this setting, it is possible, e.g., to permit only dimensions divisible by 5, so that flat steel bars can be used.

  7. Chamfer / Radius – In the Chamfer (for Chamfer layout) or the Radius (for Filleted and Rounded layouts) input field you specify the radius of the ribbed plate at the shape radii. If this value is 0, the shape radius is imported. If you have selected the create 'Insert at Slant', the radius is bridged by a slanted edge.
  8. 1st/2nd Edge - Enabled for Half or By Length stiffeners. Sets the size of the radius, round or chamfer for each side of the stiffener.
Reset Resets the parameters of every stiffeners to default values in the selected configuration.
