Abstract
A non-circular rebar used in concrete includes a square rebar, a rectangular rebar, an elliptical rebar, a trapezium rebar, a triangular rebar, and a rebar with round edges and corners. The square, rectangular, elliptical, trapezium, and triangular rebars and the rebar with round edges and corners substitute the conventional circular rebar, so that the rebars can be tied easily to save the space occupied. Since the distance of the resultant force of the tensile stresses of the rebar from the boundary of the concrete becomes smaller or the concrete protecting layer becomes thicker, the change of the shape increases the bonding between the rebar and concrete, and the safety of construction is improved. The non-circular rebar includes a smooth rebar and a ribbed rebar with a non-circular main cross-section.
