Use of a device for reinforcing concrete structures, which bridges weakened zones caused by embedded elements by means of inserted structural elements and which transmits the forces, wherein in addition to the conventional design of the reinforcement originally calculated by the structural engineer and before the concrete is cast, the embedded elements are surrounded by at least one structural element, the structural element comprises at least one anchoring and at least one tension element in the form of a straight tension rod, a curved rod or a frame, which is connected to an anchoring at both ends, wherein a force model is formed by the structural element, which strengthens the local shear behavior of the statics in the area of the embedded elements, and thus improves the concrete structure weakened by the embedded elements by transferring the forces, and reduces or eliminates the static weaknesses of the concrete structure caused by the embedded elements, the tensile element taking over shear, compressive, transverse, tensile forces and/or bending moments, wherein force-neutral zones are formed by the force model for the embedded elements, the structural element surrounds these force-neutral zones in a plane on two opposite sides at least partially and completely on a third side connecting the two sides, and the embedded elements are accomodated and held in the force-neutral zones, wherein by inserting the structural element, the weaknesses are bridged, which are caused by the embedded elements, which were not taken into account in the static design of the conventional reinforcement of the concrete structures. device for reinforcing concrete structures, which bridges weakened zones caused by embedded elements by means of inserted structural elements and which transmits the forces, wherein in addition to the conventional design of the reinforcement originally calculated by the structural engineer and before the concrete is cast, the embedded elements are surrounded by at least one structural element, the structural element comprises at least one anchoring and at least one tension element in the form of a straight tension rod, a curved rod or a frame, which is connected to an anchoring at both ends, wherein a force model is formed by the structural element, which strengthens the local shear behavior of the statics in the area of the embedded elements, and thus improves the concrete structure weakened by the embedded elements by transferring the forces, and reduces or eliminates the static weaknesses of the concrete structure caused by the embedded elements, the tensile element taking over shear, compressive, transverse, tensile forces and/or bending moments, wherein force-neutral zones are formed by the force model for the embedded elements, the structural element surrounds these force-neutral zones in a plane on two opposite sides at least partially and completely on a third side connecting the two sides, and the embedded elements are accomodated and held in the force-neutral zones, wherein by inserting the structural element, the weaknesses are bridged, which are caused by the embedded elements, which were not taken into account in the static design of the conventional reinforcement of the concrete structures.
