Stiffener

Element describing the structure concept of type stiffeners which are attached to plating and constitutes the scantlings.

Attributes

Name Type Use Description
GUIDRef ocx:guid optional A globally unique ID referring to an entity in the authoring application. The sending application creates and holds the GUID. Used to establish a unique reference to an entity persistent between applications.
functionType ocx:functionType optional The structure function type giving the structure property function. Follows STEP AP218 coding and IACS Rec 82 Glossary. Enumerator of structure functions which shall be assigned to the parent structure concept.
id xs:ID required An identifier for an element unique within the scope of the XML file. Each id must be unique within a document. The attribute uses the standard XML 1.0 ID type as defined in the XML Schema specification. This attribute is required in many OCX XML elements and an application should generate them automatically.
name xs:string optional An optional descriptive or display name.
orientationRule ocx:orientationRule optional The orientation rule for the stiffener. The rule is used to orientate the stiffener together with the Inclination. The stiffener Inclination determines the orientation of the flange and the web side.

Children

Name Type Cardinality Description
TraceLine TraceLine [1, 1] The landing curve on the moulded panel surface represented by any Curve3D type.
MaterialRef ocx:MaterialRef_T [1, 1] A reference to a material in the catalogue
SectionRef SectionRef [1, 1] A reference to the parents cross-section.
Inclination ocx:Inclination_T [1, ∞] The inclination of the cross-section of a stiffener or a pillar along its trace line. A vector pair giving the local orientation of the web and flange directions at the point given by the Position element. The FlangeDirection is optional and not necessary for a symmetrical cross-section. Only one inclination is necessary for a non-twisted (straight) stiffener or pillar.
EndCutEnd1 ocx:EndCut_T [0, 1] The stiffener end cut detailing.
EndCutEnd2 ocx:EndCut_T [0, 1] Stiffener end cut detailing at end 2.
Offset ocx:Quantity_T [0, 1] An offset from a reference plane or surface. A positive offset value is in the direction of the surface normal vector. Give an Offset=0 if there is no offset from the referred object.
ConnectionConfiguration ConnectionConfiguration [0, 2] The structural concept defining the end configurations for stiffeners used in shipbuilding.
Penetration Penetration [0, ∞] Structural concept of stiffener penetration configurations typically used in shipbuilding.
CutBy ocx:CutBy_T [0, 1] A structural concept defining a cut-out in a surface defined by a parametric hole or a set of generic trim curves.
LimitedBy LimitedBy [0, 1] The references to limiting objects forming a closed contour of the parent element. It is not required that the set of objects is ordered in the correct sequence.
MassProperties ocx:MassProperties_T [1, 1] The mass properties of structure objects (weight and centre of gravity). These properties are provided by the exporting application and can be used as a quality measure by the receiving application to ensure correctness of the import. Both moulded and volume properties can be provided. The volume properties represent the physical mass property of the structure part, while the moulded properties are idealised.
ExternalGeometryRef ocx:ExternalGeometryRef_T [0, 1] The ExternalGeometryRef element is used to point to an external geometry representation of the parent entity (e.g. Plate, Stiffener, Bracket, Member).
Description xs:string [0, 1] Contains a description of the component its parent represents. The description is stored as a string. You can use this element for whatever purposes you require. This element can be used inside many OCX XML elements but is optional.
CustomProperties ocx:CustomProperties_T [0, 1] Container for custom properties.
