Navigation:  Working With Beam Calculations > Steel Beam Calculations

There are very few special considerations that distinguish steel beam calculation launches from the basic beam behavior described in the preceding sections.  The only significant additional property of a steel beam is the steel material grade.  During launch of a steel beam calculation, the material grade is obtained from the name value of the native Revit parameter “Structural Material”.

Then the steel grade name is extracted from this parameter, it is automatically converted to a corresponding yield strength (in KSI) to be used for the calculation.

Similar to other design parameters, ENERCALC for Revit provides 2-way control of the steel grade.  Modifying the numerical value of the Fy yield strength to a standard steel grade value will cause the material name assigned in Revit to update automatically when the “Save and Close” operation finishes.  Note that this automatic mapping of names and yield strengths only applies if the default Revit materials (or similarly named materials) are present in the project.  Removal of default materials may inhibit the ability to set and manage the steel grade in steel beam calculations.  The mapping of these material names and grades is as follows:

** Applies only if no other specific name matches are found

When a steel beam Fy is manually changed in ENERCALC SEL, the material name parameter value will be chosen by using the same matching process in reverse.
