Abstract
The Spaniards that conquered the Andean Highlands of Latin America constructed buildings with adobe and rammed earth. For
this reason, Colombia has 90% of its heritage buildings made of earth; most of them located in high and intermediate seismic
hazard zones. Considering that these constructions are vulnerable to earthquakes, in 2019, the standard AIS-610-EP-2017 was
included in the national earthquake-resistant regulation (standard for seismic reinforcement of heritage earthen buildings). Using
this standard, two buildings built in the 16th century were analyzed. The walls were reinforced with steel plates (or wooden
elements). For seismic loads, the results suggest that only 24% of the unreinforced walls would have stresses lower than the tensile
strength of the rammed earth. In contrast, in the reinforced walls this percentage is 98%. Likewise, the stresses in the reinforcing
elements (steel and wood) are kept below the allowable limits.
