A concrete construction made by 3D concrete printing having two or more layers of cementitious material extruded one above the other, and a reinforcing structure reinforcing the two or more layers. The reinforcing structure has at least two flexible longitudinal elongated steel elements running in lengthwise direction, and one or more flexible transverse steel elements forming an angle with the lengthwise direction so that these flexible transverse steel elements are present in the two or more layers. The structure also has a positioning element for positioning the at least two flexible longitudinal elongated elements and the flexible transverse steel elements, a polymer coating or yarns making stitches. The polymer coating or the stitches are applied on the at least two flexible longitudinal elongated steel elements, on the flexible transverse steel elements and on the positioning element thereby making a bond.

A reinforced building wall includes a foundation and an anchor rod anchored to the foundation; a first stud wall disposed above the foundation; the first stud wall having a first bottom plate, a first top plate and first and second vertical studs operably joined to the first bottom plate and the first top plate; a horizontal first bridge member disposed between the first stud and the second stud, the first bridge member having a first vertical opening; a rod post having one end operably connected to the anchor rod and operably connected to the first bridge member to transfer downward forces from the first bridge member and the second bridge member to the rod post; the anchor rod is attached to an anchor; and the anchor is disposed in an upper portion of the foundation.

A concrete construction (100) made by 3D concrete printing that contains: two or more layers (102, 106) of cementitious material extruded one above the other, and at least one elongated steel element (104, 108) reinforcing at least one of the two or more layers. The elongated steel element (104, 108) is provided with a first crimp. Due to the crimp, a good anchorage in concrete is obtained and the anchorage force is predictable, since the standard deviation of the anchorage force is very small. The elongated steel element can be a single steel wire with a diameter D, the amplitude of the crimp ranges from 1.05×D to 5.0×D. The elongated steel element can also be a steel with steel filaments having a maximum diameter d. The amplitude of the crimp ranges from 1.05×d to 5.0×d.

The method for optimising the cutting of elongated products, in particular bars or profiles for reinforced concrete, comprises the steps of arranging in succession along a longitudinal feed direction (Y) a feeding area (5), a cutting assembly (3) and a measuring path (4) for the products (2), the measuring path (4) being configured to receive on a respective receiving plane (4a) the products (2a) cut by the cutting assembly (3). The method also provides for arranging a storage (6) divided into a plurality of compartments (7) downstream of the measuring path (4), for receiving the cut products (2a).

A stud weldable rebar includes a steel bar comprised of a material composition confirming to ASTM 706 which extends along an axis A from a first end to a second end. The steel bar includes a base portion disposed adjacent the first end which has a base diameter D1 to define a base cross-sectional area of the base portion. The steel bar also includes an upset portion disposed adjacent the second end which has an upset diameter D2 being greater than said base diameter D1 to define an upset cross-sectional area of said upset portion. The material composition of the steel bar is restricted to a carbon equivalency between 0.31 and 0.43, and the upset cross-sectional area is approximately 13.5% to 22.5% greater than the base cross-sectional area to provide A706 rebar that surprisingly meets both the AWS D1.1 and ACI 318 standards after stud welding.
