In the Define Liners dialog there are four different Liner Type options to choose from. These are summarized below.
Standard Beam
If the Liner Type = Standard Beam, you can define the properties of a liner which can respond to flexural, axial and shear loads.
Reinforced Concrete
If the Liner Type = Reinforced Concrete, you can define the properties of a liner which can respond to flexural, axial and shear loads. The properties of the reinforcement and concrete are defined separately, and you can view support capacity plots and safety factor for the liner components.
NOTE: see the Standard Beam versus Reinforced Concrete topic for a comparison of these two liner types.
Geosynthetic
If the Liner Type = Geosynthetic, you can define the properties of reinforcement materials such as geogrids or geotextiles, which only provide support in tension.
Cable Truss
If the Liner Type = Cable Truss you can define a cable truss support system, which only provides support in tension.
