Notes

  • ShapeBuilder can generate beam cross-sections in the shape of a rectangular section, To define a rectangular section, use the following parameters.
    1. @SHAPE_GROUP: SOLID, and
    2. @SHAPE_TYPE: RECTANGULAR_SECTION.
  • The base section is a solid rectangular section, as illustrated in fig. 1. No options are available for this shape.
  • Sectional shapes are defined in their own local coordinate system, which is assumed to coincide with the global coordinate system. If a fixed frame, FrameName, is specified, the local coordinate system coincides with this fixed frame.
  • The mesh density parameter, md, determines the level of mesh refinement. (Default: md = 4)
  • It is possible to attach comments to the definition of the object; these comments have no effect on its definition.

The rectangular section: base configuration

Figure 1. The base configuration for the rectangular section.
  • Fig.1 illustrates the base configuration of the rectangular section.
  • The geometric configuration of the rectangular section if defined by the dimensions listed in table 1, which are also indicated in fig. 1. Dimensions labeled in red are required. Dimensions labeled in blue are optional and are assigned the default value indicated in table 1.
Component Dimension Symbol Default Nb.
rectangular section width w required 01
rectangular section height h required 02
