Análise numérica de estruturas de parede de concreto: modelagem computacional do edifício residencial arbo condomínio parque

Abstract

The constant search for improvement in quality management methodologies in the civil construction market, more precisely the development market, has become highly demanding and competitive. Thus, in the face of this scenario of constant transformation and search for more effective options that would make their enterprises more economically viable, the construction system of Concrete Wall Molded in loco came to be used on a large scale by several construction companies, when in 2012 it was standardized of the Brazilian Standard 16055. With its popularization, the recurrence of the most diverse types of pathologies was observed, namely: cracks in walls at 45 ° and 90 °; cracks in slabs; concreting niches; and others, with cracks being the point of interest in this study. Thus, in view of the great socioeconomic importance of buildings built with concrete walls molded in loco, this study aims to analyze, through the Finite Element Method, a 12-floor building designed and built by a nationally renowned company, specialized in concrete wall buildings, which soon after concreting showed some cracks. In this modeling, the software © Abaqus-CAE Research V2020 was used, where each floor of the building was represented with the degree of resistance characteristic of its respective concreting cycle, which was obtained through the technological control of the concrete made in loco. We also sought to analyze the stress distribution and the deformations in the structural elements, in addition to conducting a comparative study between the stress distribution analyzed and cracks found in the post-concreting. Finally, this work should enable a better understanding of the structural behavior of this building, in addition to defining the structural factors that may cause cracks
