Answer 1

I have provided the Riveted plate Girder. I have given design for web plate, flange plate, and flange angles.

As the code to be used is not mentioned in the question, I am designing using Indian Code of Design. Please don't mind the answer if it is not relevant to you, just ignore it and don't give a negative rating.
