# # 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 how 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.
