Can steel bars be replaced by large screws in the concrete floor?
In theory, how big a round steel will have to replace the large thread steel, and if it is cast, then still better to use thread steel, screw steel tensile resistance than round steel by strong
Equal strength substitution method;The strength of the reinforcement to be replaced must be greater than or equal to the original strength of the reinforcement. The tensile strength of the original reinforcement, the square of the diameter * the tensile design strength / the diameter of the reinforcement to be replaced by the square *, the tensile design strength.
Tensile strength, extensibility, yield point! The same thread can be used instead!Of course, the number of roots must also be the same ~ only specifications vary!
