Currently, according to Bentley Support, the Material Definition properties are only used in the Connection Design module and are not used for steel design & code checking. The SGR, FYLD, FU parameters must be used instead to define the material properties. The Material Definition properties should be used for all subsequent steps. It is not optimal to define material properties more than one time.
Thank you. For this idea, we will take this to be 'Extend the capability of using the material definition as the steel grade for AISC 360-10 design, mirroring the behaviour provided for AISC 360-16.'
Thank you for posting this idea. This functionality is already used in the AISC 360-16 design code. The parameters provided will thus be overrides for any definition provided in the material definition. Were you looking for this to be added to any other specific code? It will be used as the principal for any new design codes added to STAAD.Pro, but adding it retrospectively to other codes would require significant refactoring.
