Avaliação de manifestações patológicas devido ao recalque diferencial de fundações no município de João Pessoa

Abstract

Inherent in population development linked to technological advancement is the expansion of civil construction. However, the use of new technologies in the construction field, in construction processes and materials, has not resulted, in the same proportion, in constructions with higher levels of quality or service life. A significant index of pathological manifestations of the most varied species has been identified in buildings, problems arising from poor planning, insufficient studies (geotechnical, architectural and structural) and lesser control over the production process. Pathological manifestations can occur in the most varied forms and in the various elements of the building, the most recurrent being due to the characteristics of the soil that arise from the negligence in the steps of characterizing its behavior, in addition to erroneous analysis, lack of design and poor execution of foundations, responsible for transmitting the loads of buildings to the ground. Thus, the present study seeks to evaluate the pathological manifestations due to the differential settlement of foundation in the Municipality of João Pessoa, according to reports of occurrences made to the Civil Defense of the Municipality, aiming to analyze the possible origins of repression and evaluate the anomalies of the buildings. Through this, it was possible to identify which fissures and cracks were the most prevalent anomalies according to the cases studied, in addition to the important observation of the need for geotechnical investigations and monitoring by a technical professional even in small works, to avoid major problems such as collapse of the structure.
