RESUMEN: El presente artículo tiene como objetivo principal comprender el comportamiento dinámico de edificaciones históricas y culturales de adobe y tapia pisada y proponer posibles alternativas de rehabilitación sísmica. Para el efecto, se adelantaron una serie de ensayos dinámicos sobre mesa vibratoria, realizados sobre modelos de viviendas a escala reducida construidos en adobe y tapia pisada. Con base en las reglas de la mo- delación física a escala, se diseñaron y construyeron un total de 4 modelos en escala 1:5, los cuales se rehabi- litaron mediante dos alternativas de reforzamiento previamente definidas. Una de las alternativas de estudio seleccionadas consiste en el reforzamiento mediante elementos de madera horizontales y verticales, actuando a manera de elementos de confinamiento de los muros. Otra alternativa estudiada se fundamenta en la coloca- ción de malla en acero de refuerzo adosada a los muros y recubierta con un mortero de cal. ABSTRACT: The present article has as principal objective understand the dynamic behavior of historical and cultural constructions of adove and tapia pisada and to propose possible alternatives of seismic rehabilitation. For the effect, a series of dynamic tests went ahead on vibratory table, made on models from houses on re- duced scale constructed in adove and tapia pisada. With base in the rules of the physical modeling on scale, a total of 4 models in scale 1:5 was designed and constructed, which were rehabilitated by means of two alter- natives of reinforcing previously defined. One of the selected alternatives of study consists of the reinforcing by means of horizontal and vertical wood elements, acting to way of confinement elements of the walls. Another studied alternative is based on the positioning of steel of reinforcement mesh leaned to the walls and covered with a lime mortar.
