Análise estrutural e desempenho de um silo convertido em edificação habitacional

Abstract

This paper presents the structural retrofit of the "Moinho" silo in Recife Antigo, converted into a residential building that preserves its historical heritage and complies with current technical standards. The objective of this study was to investigate the challenges and technical solutions adopted in this retrofit process, contributing to the advancement of knowledge about interventions in historic structures. The research involved direct data collection on site, application of non- destructive testing to assess concrete strength, computational modeling for structural simulation, and comparative analysis with Brazilian standards. Sections 1 and 2 were reinforced with embedded slabs, chamfered casing, and grouting of exposed reinforcement, ensuring structural stability and safety. Section 3, due to its compromised condition, was demolished and rebuilt with rigorous planning to preserve the integrity of the remaining structure and the safety of workers. Continuous monitoring, through technical inspections and data validation, ensured regulatory compliance and economic viability. Daily monitoring of the demolition was essential for identifying critical points and sizing reinforcements, optimizing interventions. The study contributes to civil engineering by documenting a practical case study of structural rehabilitation in a historic building, demonstrating the importance of integrating technical analysis, on-site monitoring, and simulation technologies. The Moinho project reaffirms that the preservation and adaptation of old buildings, when conducted based on sound technical criteria, can result in projects of high architectural, functional, and economic value, reconciling historical memory and construction innovation.
