In this research, the seismic retrofit of a reinforced concrete building with more than 50 years old is proposed. The structure is made up of frames and walls, having a construction area with 1980 m2 and 4 stories with a total height of 15.50 m. In addition, three kind of reinforcement are evaluated for the old structure, giving as a final proposal for reinforcement one of the alternatives presented. The first reinforcement alternative consists of the use of Steel Jacket with post-installed bolt anchors of Carbon Fiber Reinforced Polymers (CFRP) in columns, the second alternative consists of the use of CFRP jacket with CFRP anchors in columns. while the third alternative consists of the use of CFRP sheets diagonally with CFRP anchors at their ends to ensure that these sheets resist up to their high stress levels. These anchors together with the diagonal sheets contribute to give the wall ductility and in turn resist the effects of sliding at the base, a failure that is very common in rigid structures such as walls. Each non-conventional reinforcement methodology used in this research is validated through the results of laboratory tests of reinforced columns and walls using the techniques of each of the three alternatives mentioned. Non-linear static analysis - Pushover of each reinforcement alternative was performed and it was compared with the demand of the 1974 earthquake in Lima. There have been 3 seismic records and a PGA of 0.45g which is the design acceleration in Lima. It is shown that these proposals are effective for the levels of shear capacity and displacement in the inelastic design. For the columns of 0.40mx0.80m the results show that both reinforcements increase the ductility by more than 10%; On the other hand, the proposal of reinforcement in the walls of 40 cm of thickness, has obtained a better result in 100% and in the base in 100%.
