ANÁLISE ESTRUTURAL DE UM MURO DE ARRIMO EM ESTRUTURA MISTA EM CONCRETO ARMADO E BLOCO ESTRUTURAL: estudo de caso em João Monlevade, Minas Gerais

Abstract

This study analyzes the structural performance of a mixed-construction retaining wall located in João Monlevade, Minas Gerais, with the aim of identifying the causes of the instability observed in the structure. The investigation was carried out through a technical site visit, field data collection, interviews, geotechnical analyses, and structural modeling using the software Ftool®, PCalc-1.4®, Excel®, and FlexCisTor®. The research assessed the behavior of the masonry panels, columns, capping beam, and the soil–structure interaction, verifying whether the components exhibited adequate resistance to the applied loads. The results revealed significant deficiencies in the performance of the masonry, reinforcement, and foundation system, indicating that the wall did not meet the minimum stability requirements expected for structures of this type. The integrated analysis showed that the combination of the absence of an adequate structural design, undersized elements, and a foundation unable to provide sufficient stiffness directly contributed to the displacements and the onset of overturning.
