How to designate a beam as fully restrained or braced in STAAD ?
(OP)
I have to design a steel I-beam which is placed on a concrete slab upon which (I-Beam) load of skylight has to come. I want to take advantage of bottom concrete surface on which beam is placed directly. So, where can I give the command of fully restrained member to Staad? Second should I design the member like that or there should be different procedure?

I'm not sure I understand completely your issue. Is the steel beam spanning anything? A skylight is usually a fairly light load with only wind load and/or snow load really affecting its attachment and supports. A sketch would be helpful.

I have attached the autocad file. Pardon me with the drawing I know its only a demonstrating one. Hope you would find it helpful.

UNT Member Length Unsupported length of the top* flange for calculating flexural strength. Will be used only if compression is in the top flange.
UNB Member Length Unsupported length of the bottom* flange for calculating flexural strength. Will be used only if compression is in the bottom flange.
I believe these commands can be found under the "design"-"steel"-"define parameters" tabs. using the GUI. These parameters are entered into the program using a length variable for example:
UNT 5 MEMB 11 TO 18
This command will give a unbraced length of 5 length units (feet or inches) to top flange of members 11 to 18.
