Approximately one fifth of the world's population and some 35 million people in South America inhabit adobe and rammed earth constructions. These buildings have demonstrated poor seismic behavior in earthquakes occurred over the last 50 years all around the world generating thousands of casualties. In addition, in Colombia a large number of historic and cultural earth built constructions are located on high seismicity zones. With these precedents, an investigation orientated to establish the seismic behavior of these constructive types, and propose seismic rehabilitation alternatives, viable from the technical point of view. The two proposed alternatives, the one with wire mesh and mortar and the other with wood confining elements, prove their feasibility, showing the second one, better relative seismic behavior.

Keywords : Adobe and rammed earth buildings; seismic rehabilitation; experimental research.
