Steel structure details
Thread Content
What are the round holes for tension bars and the oval holes for connections on C-shaped steel used for? Can channel steel be used for roof ridges? At what span length is a central column necessary? Must high-strength bolts be used to connect beams and columns made of H-shaped steel? Does the term \"scissor braces\" refer to the tension bars?
Look at the two parallel vertical plates beneath the column for the shear braces; the round holes are positioning holes, while the oval holes are displacement holes. The roof ridge can be made of channel steel; yes, high-strength bolts are required due to the large shear forces. As for the shear braces, they are probably those diagonal braces that cross each other – I’m not entirely sure about this. I hope this information is useful to you.
As for the central column, it depends on the strength of your beams and columns; I’ve seen projects with a span of 30 meters that didn’t have any columns in the middle
