Structural element

In structural engineering, structural elements are used in structural analysis to split a complex structure into simple elements (each bearing a structural load). Within a structure, an element cannot be broken down (decomposed) into parts of different kinds (e.g., beam or column).

Structural elements can be lines, surfaces or volumes.

Line elements:


 * Rod - axial loads
 * Beam - axial and bending loads
 * Pillar
 * Post (structural)
 * Struts or Compression members- compressive loads
 * Ties, Tie rods, eyebars, guy-wires, suspension cables, or wire ropes - tension loads

Surface elements:


 * membrane - in-plane loads only
 * shell - in plane and bending moments
 * Concrete slab
 * deck
 * shear panel - shear loads only

Volumes:


 * Axial, shear and bending loads for all three dimensions
