Between the years 2001 and 2003 the Materials and Structures Research Group grime, carried out technical inspections of the construction systems of the buildings that were declared national heritage in the Colombian Andean zone –many of them made with adobe–. Based on the results of this study, three adobe walls, representative of the religious buildings of the Andean region, were constructed and subjected to pseudo-dynamic cyclic loads parallel to their main plane. Based on the results of these tests the characteristics of the behaviour of the walls under cyclic loads applied in their main planes were established. Later, two retrofitted walls with steel tensors were constructed and subjected to loads parallel to their main plane. The retrofitting alternative improved the behaviour of the adobe walls maintaining the integrity of the wall
