Navigation:  Working With Beam Calculations > Concrete Beam Calculations > Changing Material Props in ENERCALC

Prior to launching a concrete beam calculation, the user must assign material properties to the Revit beam element.  This process is described in  Concrete Material Properties and Rebar Material Properties.

 

Once a concrete beam calculation has loaded in the ENERCALC interface, the concrete and rebar material properties will be exposed to view and modification by the user.  

 

 

 

 

If the user manually modifies the material properties, then the new values will be applied to the Revit model in one of two ways:

 

 

1.)  If an existing material definition found in the Revit project has matching properties, then the matching definition will be applied to the concrete beam on "Save and Close".  In the example shown here, the compressive strength is changed to 4.0 ksi and the modulus of elasticity is given a corresponding calculated value:

 

 

 

Viewing the "Design Properties and Rules" menu, it can be seen that a matching definition exists in the Revit model:

 

 

 

 

When the "Save and Close" operation concludes, the "Design Properties and Rules" menu indicates that the beam has been automatically reassigned to have the existing definition that matches the properties set in the ENERCALC interface:

 

 

 

 

 

2.)  If there is no existing material definition found in the Revit project with properties that match the value assigned in ENERCALC, then a new definition will be created and applied to the concrete beam on "Save and Close".  In the example shown here, the compressive strength is changed to 8.0 ksi and the modulus of elasticity is given a corresponding calculated value:

 

 

 

 

 

Viewing the "Design Properties and Rules" menu, it can be seen that no matching definition exists in the Revit model:

 

 

 

 

When the "Save and Close" operation concludes, the "Design Properties and Rules" menu indicates that a completely new definition has been created in the Revit project and the Revit beam element has been automatically reassigned to have the new definition with the properties set in the ENERCALC interface:

 

 

 

 

The provisions and behaviors outlined above also apply to rebar material definitions.  An example of revised rebar properties is shown below:

 

 

 

 

When the "Save and Close" operation for this calculation concludes, the user will observe that a new rebar material definition has been automatically created in the Revit project and assigned to the Revit beam element:
