Design code

Question

Staad has been configured to AS4100. However, third party model received uses US-AISC. When this model was run and STAAD is looking for US-AISC LRFD. How to override this so STAAD used configured AS4100.

Hi Mohamed, 
 
You might be using an older STAAD.Pro version than the third party model was created with. If so - your version does not recognize the input CODE AISC UNIFIED 2010, and to perform design to AISD code, you will need to enter the design code your version supports, through the Input file, or GUI.

On reading your problem statement it appears that the model that you received from the third party has design commands that relate to the US code and you would want to check the design as per the AS4100 code. For that you would have to change the way the design is set up. Open up the STAAD.Pro editor ( From the top menu choose Edit > Edit Input Command File ) and look for design commands as shown next 
 
PARAMETER 1 
CODE AISC 
… 
 
Or 
 
PARAMETER 1 
CODE AISC UNIFIED 2010 
 
The above would instruct the software to check as per US codes. To instruct the software to design as per AS4100 code, you may replace the above by following commands 
 
PARAMETER 1 
CODE AUSTRALIAN 
 
If there are no additional design parameters in the third party file, you should be good to go. However if there are additional design parameters specified in the file as per the US code, these may not be valid for the Australian code. So you need to find out the Australian equivalent for these design parameters and change those too. For details on the AISC code parameters you can go to Technical Reference > American Steel Design and look for Design Parameters for the appropriate code. Same for the Australian code would be available under International Design Codes > Australian Codes > Steel design as per AS 4100 > Design Parameters
