Structural elements are used in structural analysis to split a complex structure into simple elements. 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 See also Load-bearing wall Post and lintel Stressed member engine References Structural analysis Hardware (mechanical)
