DEAR SIR,
I HAVE ATTACHED A IMAGE SO INEED TO CLARIFY THE LOAD RELEASE PLEASE CONCEPT IN STAAD .
Hello Mansoor Ali,
From the screenshot I can see that you are using a very old version of STAAD.Pro i.e. SS4. We are in the process of stop supporting all V8i versions very soon. I would request you to please upgrade to the latest versions i.e. 22.00.00.15 and take full advantage of this software. You can find the process of upgrading in the below link.

If you have any question regarding this upgradation please let me know, I will assist you.
Now coming back to your question, are you talking about member release? Because, there is no command known to me as load release. If you are interested in member release please refer help manual.
