This construction type is used as a single-family house. It is a single-story, detached building, found in the rural and suburban areas of the province of San Juan. This traditional type of construction is built with adobe walls and no cornice. The traditional adobe house has a range of deficiencies: weak connections, heavy roofs, adobe blocks that deteriorate (especially at the base of the walls) due to prolonged exposure to humidity. This housing type is expected to perform poorly in earthquakes.
Report # 152 : Base Isolation of Confined Masonry
by Noemi Graciela Maldonado, Dr. Miguel Eduardo Tornello
Most of Argentine Republic territory may be considered seismic.Great Mendoza is an important social-economic area in the mid- western region and it has the greatest seismic risk in the country. In the last 200 years or so, there have been important earthquakes affecting building structures. Consequently, new techniques aimed at controlling vulnerability must be developed. Methodology: An investigation of the actual application of Basal Seismic Isolation (BSI) on a building ‘Students’ House’ belonging to the Technological National University (UTN) is implemented. Research of the isolation system for near source motions has been done. The construction of three modules of student houses has been done in 2004, with confined masonry and reinforced concrete for three levels and prestressed slabs. Both buildings have accelerometers to register earthquake effects. The complex is completed with a building of two levels for administration with confined masonry. The aim is to control BSI displacement. The strategy proposed was to add damping to the isolation system within certain limits and the results are compared to similar fixed base building. To control near source displacements, additional damping is an applicable and economic strategy. Although with this strategy there is increased acceleration , it is far less than in the case of fixed base building
Report # 70 : Solid brick masonry house with composite hollow clay tile and concrete joist roof slabs
by Virginia I. Rodriguez, Maria I. Yacante, Sergio Reiloba
This housing type is found in the urban areas of San Juan province. It is a one-story, detached or semi-detached building, mainly used as a single-family house. The strength of this construction type is due to its solid brick walls confined with concrete tie-beams and tie-columns. The roof slabs are of composite concrete and masonry hollow clay tile construction, which form a diaphragm tied to the walls. The deficiency of this type of construction is found in the slabs which suffer serious deterioration due to the effects of humidity. This housing type is expected to have good seismic behavior.
Report # 2 : Traditional Adobe House with Reinforcement
by Virginia I. Rodriguez, Maria I. Yacante, Sergio Reiloba
This construction type is a single-family house. In general, it is a single-storey building, an isolated construction found in the rural areas of San Juan and Mendoza. The traditional adobe block masonry walls are reinforced with foundations and plinth structure, which provide structural strength. A deficiency in this type of construction is that the adobe blocks deteriorate due to prolonged exposure to humidity.
Report # 1 : Confined Block Masonry House
by Virginia I. Rodriguez, Maria I. Yacante, Sergio Reiloba
This is typically a one-or two-story residential building of detached or semi-detached construction, generally found in the urban areas of San Juan and Mendoza, and less frequently in the rural areas. The walls are made of concrete block masonry with reinforced concrete columns and beams that tie the walls together and provide strength for the building. One of the main structural deficiencies for this construction type lies in the widely different wall densities in the two orthogonal directions. This deficiency may be eliminated with appropriate architectural design. This construction type is otherwise expected to demonstrate good seismic performance.
