Wall properties
Wall properties are similar to column properties though instead of width, depth and angle there is thickness. The fixity settings are somewhat different, and there is no Bending Stiffness Factor.
General
The following is a list of RAM Concept general wall properties:
Setting | Description |
---|---|
Concrete Mix | Type of concrete used (defined in Materials Specification). |
Height | Vertical distance from centroid of slab element to far end of wall. |
Support Set | Defines the wall as below or above the floor. |
Thickness | |
Shear wall | "Locks" the wall to the slab horizontally and thus restrains it; otherwise, the slab can "slide" over the wall. |
Fixed Near | Provides a moment connection between wall and slab about the wall’s r-axis; otherwise pinned. |
Fixed Far | Provides a moment connection about the wall’s r-axis at far end; otherwise pinned. |
Compressible | Allows for the wall to elongate in the z-direction according to Hooke’s law; otherwise incompressible. Compressible walls usually produce results that are more accurate. |
Meshing
The following is a list of RAM Concept meshing wall properties:
Setting | Description |
---|---|
Mesh Slab Support Region | When checked meshed elements are generated within and bounded by the wall shape. |
Slab Support Region Stiffness Factor | The entered multiplier is used to factor the flexural stiffness terms (KMr, KMs, and KMrs) for the meshed slab elements that are generated in the support region. The default value is 10, which will result in a nearly rigid zone over the wall. Consideration of such a stiffened zone may be important for accurate deflection prediction. |
