Slab deflection settings
The Slab Deflection page and its subpages allow you to control the slab deflection defaults applied:
- In the current project - when accessed from the Slab Deflection Settings dialog on the Slab Deflection tab.
- In new projects - when accessed from the Settings dialog on the Home tab.
Slab deflection settings when accessed from the Slab Deflection Check Catalogue
Button, command, or option | Description |
---|---|
New Load Event Defaults subpage |
|
Start time offset |
Allows you to define a default start time offset value for new event load start times. The value of a new event load start time is always the previous event start time + the default start time offset. |
Construction load |
Allows you to define a default value for new construction loads. Note:
The default construction load value depends on the head code that you are using. |
New Check Defaults subpage |
|
Deflection limit, L / |
Allows you to define a default deflection limit to new checks added to the When a new check is added to the Slab Deflection Check Catalogue it initially defaults to the deflection limit set here. |
Aging, Creep & Shrinkage subpage |
|
Allowance for shrinkage effects in total deflection |
Allows you to define an amplification base factor for shrinkage. Note:
The value must be within the range from 0.1 to 0.9. |
Aging Coefficient |
Allows you to select between 2 creep/aging methods: User defined and Automatic. Note:
The Aging Coefficient option is only available for the US head code. |
Modification Factors subpage |
Allows you to adjust the properties used for the different element types in the iterative cracked section analysis. |
Iteractive Cracked Section Analysis subpage |
|
Global Convergence Criteria |
Allows you to modify the following options:
Tip:
To resolve global convergence failures:
|
Local Convergence Criteria |
Allows you to modify the following options:
Tip:
To resolve local convergence failures:

Load Event Sequence subpage |
Allows you to modify the global event sequence according to your needs. Tip:
The global event sequence provides the basis for the model event sequence that you can modify, whereas the model event sequence provides the basis for a submodel event sequence that you can modify. |
