STAAD.Pro Help

RAM Connection Material Database dialog

Used to review additional material data required by Connection Design for the design of steel connections. Material strengths are displayed here to allow for the assignment of material grades.

Opens when Connection Design >  Show RAM Database is selected.

Additional material data is required by RAM Connection beyond that which is kept in STAAD.Pro's databases. This information can be viewed and edited from the RAM Material dialog. In the case of the same material being defined in both STAAD and RAM Connection, the local STAAD value is used.

The STAAD materials are read from the STAAD.Pro .ini file. Some generic materials do not have any strength materials defined and these should be entered here.

Materials listed in the country tabs (i.e., United States or United Kingdom) are read from RAM Connection. These values are displayed in yellow fields and may not be edited in this dialog.

SettingDescription
Materials table

The following explains the columns used in the RAM Materials table:
