Spanish abstract Se describen los principales componentes y arreglos de mampostería histórica, vulnerabilidad sísmica y técnicas existentes de refuerzo, principalmente presfuerzo. Tomando como base la evolución del presfuerzo, se presenta una perspectiva futura sobre su uso en la herencia cultural. Se requiere atención especial al usar esta técnica, ya que la resistencia a compresión puede ser excedida, presentando una falla frágil y explosiva. La aplicación correcta requiere el diseño de un dispositivo compatible con fuerza de post-tensionado óptima que mejore resistencia y ductilidad sin dañar la estructura
English abstract Unreinforced masonry is one of the oldest construction materials and main component of historical buildings. Masonry is a heterogeneous material with an anisotropic behavior and may fail quasi-brittle during earthquakes. This paper describes the main components and arrangements of historical masonry, seismic vulnerability and existing retrofitting techniques, especially prestressing. Based on the evolution of prestressing, it is developed a future perspective about the use of this technique on cultural heritage. Especial attention may be taken into account when using this technique because the compressive strength may be exceeded, leading to an explosive brittle failure. The correct application of prestressing requires the designing of a compatible device and optimal post-tensioning force that improves strength and ductility without endangering the structure
