General wall properties
| General | |
|---|---|
| Name | The automatically generated name. |
| User Name | Can be used to override the automatically generated name if required. |
| Top Level | Specifies the top level for the wall. |
| Base Level | Specifies the bottom level for the wall. |
| Wall Type |
• Meshed Shear Wall |
| Material type |
|
| Assume extra floors supported | Enter the number of extra floors supported. |
| AutomaticGenerate Support |
• Cleared - a support will only be created if the Generate support property is checked. • Checked - a support will only be created if no members/slabs capable of providing support exist under the wall. |
| Generate support |
• Cleared - no support is created under the wall. • Checked - a support is created under the wall. Note: When a support is created, a line support is formed under a
meshed wall, a point support under a mid-pier wall, and a series
of point supports under a bearing wall.
Note: When a support is created, its degrees of freedom are as
specified in the ‘Wall support’ area of the wall
properties.
|
| Plane | Indicates the grid along which the wall is placed. |
| All panels | |
|---|---|
| Grade | The grades that are available for General materials are set from the Materials button on the Home ribbon. |
| Thickness | The thickness of the wall. |
| Alignment |
Alignment of the wall:
|
| Alignment offset | When the alignment is set to User it can be adjusted by specifying an exact offset. |
| Assume cracked |
Assuming concrete sections are cracked has a direct affect on the analysis; smaller Modification Factors are applied to cracked sections causing an increase in deflection. Indirectly the design can also be affected because the sway/drift sensitivity calculations are also influenced by this assumption. |
| End 1 extension |
The amount the wall is extended or trimmed back from end 1. • A positive extension extends the wall length beyond its insertion point. • A negative extension trims the wall back from the insertion point. |
| End 2 extension |
The amount the wall is extended or trimmed back from end 2. • A positive extension extends the wall length beyond its insertion point. • A negative extension trims the wall back from the insertion point. |
| Releases | |
| Minor Top |
• Fixed • Pinned • Continuous (incoming members pinned) |
| Minor Bottom |
• Fixed • Pinned • Continuous (incoming members pinned) |
| Sway and drift checks | |
| Merge with stack below |
Columns are divided into stacks and walls are divided into panels at floor levels where members or slabs connect to the column/wall. For the purposes of Sway/Drift, Wind Drift and Seismic Drift checks only you can override the default stack/panel divisions by merging a stack/panel with a lower stack/panel. The length of the combined stack/panel is then used in the checks. |
| Sway/Seismic drift checks |
By default all stacks of all walls are taken into account in the calculation to determine the sway sensitivity of the building. The results of this calculation being accessed from the Review toolbar. This parameter provides a facility to exclude particular wall panels from these calculations to avoid spurious results associated with very small panel lengths. You can either clear the checkbox located under ‘All Panels’ to exclude the entire wall, or you can exclude a particular panel by clearing the checkbox located under that panel only. |
| Wind drift check, Wind drift ratio |
Wind drift is automatically checked against the specified limiting ratio, (which can be set differently for different columns). The results of this calculation are accessed from the Review toolbar. If you don’t want this check to be performed you can either clear the checkbox located under ‘All Panels’ to exclude the entire wall, or you can exclude a particular stack by clearing the checkbox located under that panel only. |
| Panel 1, 2, 3 etc. | |
|---|---|
|
In a multi-stack wall properties can be entered for a specific panel, over-riding those defined at the All panels level. |
|
| Count the floor as being supported | |
|---|---|
|
Top level (Interediate levels) Base level (Head Code Eurocode, BS or IS) |
If checked, the floor will be treated as supported when calculating the live/imposed load reductions. |
| Restrained | |
|---|---|
|
|
Used to indicate at which levels the wall is restrained. Note: Only levels with a connecting member are listed.
|
| Meshing | |
|---|---|
| Override Model’s | Select this checkbox to override the default wall mesh size that is specified in the Structure properties. |
| Wall Mesh Horizontal Size | Used to override the default wall horizontal mesh size (1.000m). |
| Wall Mesh Vertical Size | Used to override the default wall vertical mesh size (1.000m). |
| Wall Mesh Type |
