- The Use of Prestressing Through Time as Seismic Retrofitting of Historical Masonry Constructions: Past, Present and Future Perspective Adolfo Preciado Gianni Bartoli Harald Budelmann Multidisciplinarias (Ciencias Sociales) earthquakes old masonry Prestressing retrofitting smart materials 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. 2015 artículo científico 1405-0269 https://www.redalyc.org/articulo.oa?id=10441539008 en http://www.redalyc.org/revista.oa?id=104 CIENCIA ergo-sum, Revista Científica Multidisciplinaria de Prospectiva application/pdf Universidad Autónoma del Estado de México CIENCIA ergo-sum, Revista Científica Multidisciplinaria de Prospectiva (México) Num.3 Vol.22
