Colombia is located in the Andean Zone, a point at which multiple layers converge Tectonics, turning this into one of the most seismically active regions on Earth. Witness Of this are the earthquakes occurring in the coffee axis in 1999, Popayán in 1983 and Cúcuta in 1821; Which caused the collapse of multiple structures, generating incalculable losses. Much of the Colombian historical centers were built on land, using technical Inherited from the Spanish invasion; such as the buildings of Tapia, Adobe and Adobe; Materials that have a poor response to stress and cutting efforts. The continuous seismic threat of the area, the materiality of these structures, the multiple Interventions and changes of uses that have been endowed to these buildings over time, Makes these constructions highly vulnerable to a seismic event, putting in Risk the life and property of the inhabitants. Therefore, solutions should be raised to improve their Structural performance before this type of event, which is respectful of the values Heritage of the building as part of the historical memory of the country. This thesis aims to study and the structural compression of this type of architecture, before the Seismic and service charges. By implementing advanced calculation methodology and Specialized software, the structural behavior will be analyzed, simulating multiple hypotheses In the event of an earthquake. In this way propose solutions that improve the performance Structurally, minimizing its seismic vulnerability. As a practical purpose of this TFM will study the Specific case of the Zarama house; An old house of Republican style, two floors and 2200 m2 of area, built in Tapia treaded at the beginning of the eighteenth century, located in the historical center of the City of Pasto, capital of Nariño (southern Colombia).
