The article presents a way to increase the load-bearing capacity of a reinforced concrete column due to metal clips from the corners with an increase in the load on it. To ensure the joint operation of the existing column and the metal cage, the corners are subjected to prestressing, which is achieved by compressing the corners with jacks.

The article presents a new design of reinforced concrete I-beam coverage with prestressed reinforcement, in which the ribs are stretched zone side ledges. This solution allows you to pick off high-strength prestressed reinforcement along the length of the element, thus increasing the ratio of reinforcement used in comparison with a standard solution
