BEAM12

Format

<BEAM12
       id       = "integer"
       pid      = "integer"
       g1       = "integer"
       g2       = "integer"
/>

Attributes

id

Unique element identification number.

pid

Property identification number.

g1

First grid identification number.

g2

Second grid identification number ( $\text{g1}\ne \text{g2}$ ).

Example

The example demonstrates the definition of a BEAM12 element.

<BEAM12 id="5" pid="12" g1="20" g2="6"/>

Comments

1. The fully parameterized NLFE beam element is a type of line element that has two nodes.
2. Each element has a unique identification number with respect to other NLFE circular beam elements.
3. This element can resist the axial, shear, torsion and bending loads.
4. The element has a deformable cross sectional area.
5. Linear and nonlinear general elastic material models can be used with the beam element.
6. The figure below shows the NLFE beam element and its nodal coordinates.

7. PBEAML and PBEAMA can be used to define the geometric properties and material card ID of the element BEAM12.
8. The dimensions of the cross section can be changed linearly in the axial direction.
