Construction practice shows that in addition to the need to strengthen the supporting structures of buildings and structures, there is a need for repair and restoration work of reinforced concrete power transmission line supports. With local damage, followed by corrosion of the internal reinforcement, which plays the most important role in containing the resulting bending moments, modern reinforcement methods are either expensive or impossible to perform. In this scientific work, a proposal is presented to strengthen such structures by replacing damaged metal rods with new ones, while new rods are connected to existing special ferrules. The reinforcement process ends with the sealing of damaged areas with high-strength putty. The paper presents the amplification technology and presents all the positive properties of the new amplification method.
