# 1D Element Loads

The beam loading modules are used to specify the load on all 1D elements. However not all loads can be applied to all element types. The tables below indicates the way in which loads are handled depending on the element type.

The beam loading is applied in four tables in GSA. These are further broken down here as

Beam Loads

  • Point force
  • Point moment
  • Distributed force – uniform, linearly varying, patch, trilinear
  • Distributed moment

Prestress

  • Prestress – prestress force
  • Initial strain
  • Lack of fit
  • Tendon – tendon prestress
  • Tendon with offset

Distortions

  • Translational distortion
  • Rotational distortion

Thermal

  • Uniform thermal
  • Thermal gradient

# Beam elements

There are no restrictions on beam elements. All load options apply to beams.
