Stiffener Type: Select the shape of the stiffening ring.

Stiffener Information

Ls: The vessel length that the stiffener is designed to support. This is determined as half the length from the center of the stiffener to the next line of support on one side plus half the length from the center of the stiffener to the next line of support on the other side.

As: The cross-sectional area of the ring stiffener by itself. This value is calculated unless the "Stiffener Type" is User Defined.

d1, d2, t1, t2: The dimensions for the cross-sectional area of the ring stiffener. These values are represented in the picture in the input form and most are available for input except when the "Stiffener Type" is User Defined.

Description: A description of the shape of the stiffener. This field will be automatically completed when the Structural Shape Search is used to select a standard structural shape.

Available Moment of Inertia: The moment of inertia of the cross-sectional area of the ring stiffener by itself around its neutral axis parallel to the shell axis. This value is calculated unless the "Stiffener Type" is User Defined.

Distance – Shell to Neutral Axis: The distance from the outside of the host shell wall to the neutral axis of the ring stiffener cross-section. This value is calculated unless the "Stiffener Type" is User Defined.
