Define Wall Units

Geometrical Parameters

Modular walls

For Modular wall units, you can define the following block parameters:

• Block height
• Block depth
• Block width
• Center of gravity
• Unit weight

Wrap-around walls

If the wall type is Segmental, you can also select Type = Wrap-around to model a wrap-around wall.

• When defining a wrap-around, you only need to specify the height of the layer.
• You can then assign this wall unit to the wall section profile, where it can be assigned to multiple layers to make up the height of the wall.

Gabion walls

For gabion walls, the wall units represent gabion baskets.

• Basket height
• Basket depth
• Basket width
• Unit weight

Shear Strength Parameters

For internal sliding, the shear strength of the interface between adjacent layers of wall units is assumed to take any of the following functions:

Constant

Input a constant shear strength.

Linear

• τ_min is the minimum shear strength
• τ_max is the maximum shear strength
• λ is the interface shear angle

Bilinear

• τ_min is the minimum shear strength
• τ_max is the maximum shear strength
• τ_tangent is the tangent strength
• λ₁ is the interface shear angle corresponding to the first line segment
• λ₂ is the interface shear angle corresponding to the second line segment
