Design and check patches
When that the slab item designs resulting from the slab or mat design process are satisfactory, you can then proceed to design patches. You should design slab items before designing patches, as the additional patch reinforcement requirement takes account of the existing level of reinforcement provided by the slab items.
Note:
For each strip within each patch, Tekla Structural Designer determines the area of the required steel (A s,reqd) and the area of the provided steel (A s,prov). The A s,prov calculation always considers the patch reinforcement, but if necessary and allowed, you can also include additional background reinforcement in the calculation.
Check an individual patch
Check all patches in the model
The same command can be
accessed in two ways:
- In a 3D Structural View, right click on the background and choose Check Patches from the context menu.
- In the Project Workspace Structure tree, right-click on the Structure branch and choose Check model patches (command) from the context menu.
Tekla Structural Designer checks the reinforcement of all patches in the model.
Check all patches on a single floor
Design an individual patch
Design or check all patches in the model
The same command can be
accessed in three ways:
- On the Design tab, click
Design Patches - In a 3D Structural View, right click on the background and choose Design Patches from the context menu.
- In the Project Workspace Structure tree, right-click on the Structure branch and choose Design model patches (command) from the context menu.
Tekla Structural Designer designs or checks all patches in the model according to their autodesign settings.
