Between the years 2001 and 2003 the Materials and StructuresResearch Group grime, carried out technical inspections of theconstruction systems of the buildings that were declared nationalheritage in the Colombian Andean zone –many of them made withadobe–. Based on the results of this study, three adobe walls, representativeof the religious buildings of the Andean region, wereconstructed and subjected to pseudo-dynamic cyclic loads parallelto their main plane. Based on the results of these tests the characteristicsof the behaviour of the walls under cyclic loads applied intheir main planes were established. Later, two retrofitted walls withsteel tensors were constructed and subjected to loads parallel totheir main plane. The retrofitting alternative improved the behaviourof the adobe walls maintaining the integrity of the wall.
