Serviceability Parameters

 

 

 

Define stress parameters, control parameters of crack and deflection for serviceability checks.

 

Note
Concrete Serviceability Parameters are applied to beam members only.

 

 

 

From the  Main Menu select Design > Concrete Design Parameter > Serviceability Parameters

 

Select Design > Concrete Design Parameter > Serviceability Parameters in the Menu tab of the Tree Menu
