I just came into contact with steel structure, and I didn't study architecture before. I don't know some terms, whoops. So I have to ask you, hehe,

Scissors are cross braces. Because of their simple structure, direct force transmission and flexible arrangement, they can be made into pull rods or compression rods. Of course, there are herringbone brackets, π brackets, and even fractions.

Horizontal Brackets-Brackets arranged horizontally

Tie bars are mainly used to transfer forces to supports. If I am a supporter, put my hand on your shoulder and someone pushes your shoulder on the other side, you won't fall, I will support you.

Tie bars are divided into rigid tie bars (which can bear pressure or tension) and flexible tie bars (which can only bear tension). They are mainly guaranteed by controlling the slenderness ratio according to the design assumptions.

I suggest you look at the steel structure design manual or the steel structure university textbook.
