- External strengthening of unreinforced masonry walls with polymers reinforced with carbon fiber Camilo Vega Nancy Torres Ingeniería lateral loads Unreinforced masonry seismic retrofitting fiber reinforced polymers In many countries, buildings are usually made of unreinforced clay masonry walls, especially in Colombia. These constructions have low resistance and ductility, and are very vulnerable to seismic events, due to their low capacity of energy dissipation. This paper reports the results obtained from a research project that evaluates the behavior of reinforced masonry walls under lateral loads. The reinforcement was made using Carbon Fiber Reinforced Polymers (CFRP). In the test program, eight (8) clay masonry walls were built using hollow brick. Four (4) of them were 1,23 m long and 1,90 m high and the remaining four (4) were 2,47 m long and 1,90 m high. Four (4) walls were tested with a static lateral load and four (4) with a cyclic lateral load in its plane. Results revealed that the presence of the reinforcement material significantly increased the ultimate load and deformation capacity, provided that the material has a suitable anchoring system. 2018 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64358742003 https://www.redalyc.org/journal/643/64358742003/ https://www.redalyc.org/journal/643/64358742003/html/ https://www.redalyc.org/journal/643/64358742003/64358742003.epub https://www.redalyc.org/journal/643/64358742003/movil 10.15446/ing.investig.v38n3.73151 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.3 Vol.38
