“…Various countries, including Peru [16], Australia [17], Germany [18], and more recently, Colombia [19], have established regulations and guidelines for seismic rehabilitation of earthen structures. The current rehabilitation techniques include bonded fibers, mesh reinforcement, tensors, polyester fabric strips, straps, steel cables, concrete beams, mortar with textiles, and confining elements (wood and steel plates) [6][7][8][9][12][13][14][15][20][21][22][23][24][25][26][27][28][29].…”

“…Among the retrofitting techniques proposed in the literature, confinement with wooden elements or steel plates have emerged as a prominent alternative for restoration purposes in order to preserve heritage building in the long term [4,8,9,15,21,28]. These reinforcements have demonstrated outstanding results in improving the overall capacities and seismic behavior of earthen walls in comparison to other rehabilitation techniques; for instance, the maximum residual drift is at least three times lower than the classic mesh reinforcement technique [8], ensuring the integrity of the building after large earthquakes.…”

During the 16th and 17th centuries, Latin American cities adopted earthen construction techniques from European colonizers. As a result, rammed earth (RE) buildings now occupy an important place in Latin America’s cultural heritage. However, earthquakes around the world have shown that unreinforced earthen constructions are highly vulnerable. For several years, researchers in northern South America have been proposing a technique that consists of installing confining steel plates (or wooden elements) on both sides of the RE walls to form a grid. This system has shown excellent performance in controlling seismic damage and increasing strength and ductility capacity. Although researchers have tested full-scale one- and two-story earthen walls under pseudo-static loading in the laboratory, and one- and two-story earthen walls at 1:1 and 1:2 scales on uniaxial and biaxial shaking tables, the behavior of a complete reinforced module (one- or two-story) on a shaking table has never been assessed. The present study presents the results of shaking table tests performed on two-story RE modules at 1:4 scale. The experimental data indicate that the retrofit system with confining steel plates was effective in reducing the seismic damage of earthen constructions. In addition, the comparison of the results of the 1:4 scale tests with the 1:2 and 1:1 scale tests previously conducted by the researchers shows that the acceleration levels of the equivalent prototypes are in the same order of magnitude for the three scales.

López P. et al, 2020a;Ruiz Valencia et al, 2012 También proponen reforzar los muros con malla de acero con venas y cubierto con pañete. Finalmente, Liu et al, 2015 han propuesto la utilización de fibras externas para el confinamiento de los muros en tierra.…”

Análisis experimental de elementos de confinamiento para la rehabilitación de edificaciones patrimoniales en tapia pisada

La construcción en tierra es una de las técnicas más antiguas de la que se tiene conocimiento. Sin embargo, su comportamiento estructural presenta problemas de vulnerabilidad debido a diferentes variables como una mala conformación del sistema estructural y bajas propiedades mecánicas de la tierra. Es por esto que en el 2019 fue vinculada al reglamento colombiano de construcción sismo resistente la norma AIS-610-EP-2017 en la cual se estipula la evaluación e intervención de edificaciones patrimoniales de uno y dos pisos de adobe y tapia pisada. Basados en esta normativa se realizaron ensayos de flexión a vigas de tapia pisada con entramados de acero. Los resultados arrojan que un incremento del área de acero en los muros supone un aumento de al menos el 300% en la resistencia a la flexión en muros sometidos a cargas perpendiculares al plano.
