21.06: Seismic retrofit of historical earthen buildings using steel
Approximately one fifth of the world population and around 35 million people in South America live in earthen structures and specifically in homes built of adobe and rammed earth. These constructions have generally high seismic vulnerability, which has been evident in earthquakes in the last 50 years around the world. Additionally, there is a significant number of historical and cultural buildings constructed with earthen materials and located in areas of high seismicity. Considering the importance of this constructions, an investigation was conducted to assess the seismic vulnerability of this type of structures and establish steel plate retrofitting measure as a technically, functional, aesthetic and economically viable for the preservation of historical heritage. An experimental program was conducted in order to characterize the seismic performance of rammed earth structures representative of Colombia. Two full‐scale specimens that represent critical zones of this type of structures are evaluated. The models correspond to an L‐shaped rammed earth wall, the first is unreinforced and the second is retrofitted with steel plates. Four shaking‐table tests are applied to the specimens representing the hazard level of the studied area (La Candelaria, Bogotá, Colombia). The unreinforced specimen suffered severe damages under low seismic levels while the retrofitted specimen was able to keep its integrity for high seismic levels. Detailed description of both the tests and the obtained results are explained in this article. This research was financed by Colombian Ministry of Culture and the District Institute of Cultural Heritage (IDPC) through the Colombian Earthquake Association AIS. The authors are thankful with the assessment provided by the AIS600 committee and the Research Center on Materials and Civil Works CIMOC from Universidad de los Andes.
