Abstract
The paper presents the investigation conducted in a one-story-house and its rear annex which suffered severe damages due to a process of differential settlements of their foundations, flowing water in the subsoil and vibrations of the traffic of vehicles on the street nearby. The house is located in the city of Curitiba in the south of Brazil. The subsoil is composed of tropical clay and sand silty soils of Guabirotuba Formation. It is formed of pleistocene sediments in Curitiba area. The foundations of the house and the annex were in excavated small 8” diameter short concrete piles. Due to the differential settlements, a great number of cracks appeared in the house and in the annex walls. Many walls were distorted badly. Flowing water is presented in the subsoil. At the annex rear house the piles are embedded in a non-compacted fill. A concrete counterfort wall was constructed on the north border side of the site with a deficient drainage system. The damages which the house and the annex have been suffered due to the combination of geotechnical factors were such that the results were comparable of a earthquake with magnitudes M=5 to M=63/4, as the analysis showed. The studies showed valuable conclusions about the relationship between the differential settlements existing in the construction and the results of the seismic effects which are presented in the text. The house and the annex were underpinned, and their foundations were strengthened through the use of injected piles. The implications of the findings as far as the seismic aspects of the liquefaction phenomenon are concerned are discussed in the text.

Conditions of Structural Stability and Vibration Damage
New York, New York
The paper presents the investigation conducted in a one-story-house and its rear annex which suffered severe damages due to a process of differential settlements of their foundations, flowing water in the subsoil and vibrations of the traffic of vehicles on the street nearby. The house is located in the city of Curitiba in the south of Brazil. The subsoil is composed of tropical clay and sand silty soils of Guabirotuba Formation. It is formed of pleistocene sediments in Curitiba area. The foundations of the house and the annex were in excavated small 8” diameter short concrete piles. Due to the differential settlements, a great number of cracks appeared in the house and in the annex walls. Many walls were distorted badly. Flowing water is presented in the subsoil. At the annex rear house the piles are embedded in a non-compacted fill. A concrete counterfort wall was constructed on the north border side of the site with a deficient drainage system. The damages which the house and the annex have been suffered due to the combination of geotechnical factors were such that the results were comparable of a earthquake with magnitudes M=5 to M=63/4, as the analysis showed. The studies showed valuable conclusions about the relationship between the differential settlements existing in the construction and the results of the seismic effects which are presented in the text. The house and the annex were underpinned, and their foundations were strengthened through the use of injected piles. The implications of the findings as far as the seismic aspects of the liquefaction phenomenon are concerned are discussed in the text.
