For a more general description of how to change the design code setting in all versions of Ram Connection, see RAM Connection Capabilities and Modeling FAQ
1. After installing RAM Connection v9.0, converted v8 stand-alone .cnx files originally designed using the AISC-05 ASD code are switched to AISC-05 LRFD without notice.
2. Changes to the design code in Ram Connection Stand-Alone do not affect existing joints in the file.
3. Changing the design code in one file affects the design code for future connections in existing files. In other words, the design code setting is per user, not per file.
4. Changes to the either the main Hot-rolled Steel design code or the Connection design code in Ram Elements do not affect the design code used for existing connections in the model.
The connection templates associated with different codes are not interchangeable, so switching the design code could invalidate existing connections. Rather than break the existing connections in that way, it was decided to keep the original assigned code for each connection even when the assigned code is changed.
A change request has been logged to allow changes in the design code for the 4 US codes to retroactively alter existing connections, however.
Install Ram Connection 10.0 or later in order to change design codes for existing joints. Note, changing countries may still invalidate connections where there is not an equivalent connection type in both codes.
In all three cases, the design code must be set to the desired code and then new connections assign to the joints. The following article shows where to set the codes: Ram Connection Codes
