O presente documento reúne os trabalhos desenvolvidos em período de estágio curricular em ambiente empresarial no NCREP – Consultoria em Reabilitação do Edificado e Património, Lda., empresa que presta serviços de consultoria, inspeção e diagnóstico, monitorização e projeto no âmbito da reabilitação das construções. Primeiramente são apresentados os elementos que servem de base aos trabalhos desenvolvidos durante o estágio curricular, isto é, uma descrição das atividades de inspeção e diagnostico (ID) que envolvem a inspeção visual, ensaios complementares não destrutivos (NDT) utilizados e as verificações de segurança efetuadas segundo as normas preconizadas na legislação em vigor. O trabalho desenvolvido em colaboração com a equipa de trabalho da entidade acolhedora teve por base três casos de estudo: a Igreja, o Edifício Vila Amélia e a Escadaria Livraria Lello. No primeiro caso de estudo é apresentada uma descrição do edifício, a caracterização estrutural, os danos observados e as possíveis causas para a sua ocorrência. A campanha de inspeção realizada foi acompanhada por ensaios in situ que posteriormente foram analisados e alvo de comentários. O edifício inserido no 2º caso de estudo foi alvo de campanhas de inspeção e diagnóstico com intuito de aferir o seu atual estado de conservação. Daqui resulta uma caracterização geométrica e estrutural, um mapeamento de danos observados, bem como uma análise de segurança estrutural. O cruzamento de informação proveniente destas atividades serve de base para apresentação de sugestões de intervenção. Os trabalhos referentes à escadaria apresentam as potencialidades dos ensaios de identificação dinâmica (ID), que aliados à elaboração de um modelo numérico em elementos finitos conduzem quer à caracterização mecânica e estrutural de elementos sem recorrer a técnicas intrusivas, quer à identificação de possíveis anomalias através de simulações de danos. Por último, são apresentados trabalhos de otimização de processos de cálculo, nomeadamente, uma folha de cálculo em Excel capaz de agilizar a verificação à segurança sísmica de edifícios antigos em betão armado, de acordo com os métodos expeditos I e II no relatório LNEC, Sousa et al. (2019).
This document summarises the work developed during a curricular internship undertaken at NCREP - Consultoria em Reabilitação do Edificado e Património, Lda., a company that provides consultancy, inspection and diagnosis, monitoring and design services in the context of buildings’ rehabilitation. The first section focuses on the elements that supported the work developed during the internship, i.e. a description of the inspection and diagnostic (ID) activities involving visual inspection, complementary nondestructive testing (NDT) and safety checks performed in accordance with the recommended standards. The work carried out in collaboration with NCREP’s work team was based on three case studies: the Church, the Vila Amélia building and the Lello Bookstore Staircase. The first case study covers a description of the building, the structural characterization, the observed damage, and possible causes for its occurrence. The inspection works carried out was supported by in situ tests which were subsequently analysed and commented on. On the second case study, the team conducted inspection and diagnosis tests in order to evaluate its current state of conservation. This results in a geometric and structural characterization of the building, a mapping of observed damage, as well as a structural security analysis. The crossover of the information obtained through these activities serves as a basis for presenting suggestions for subsequent intervention. The Lello Bookstore Staircase work presents the potential of dynamic identification tests (I&D), which alongside the elaboration of a numerical model in finite elements, lead either to the mechanical and structural characterization of elements without using intrusive techniques, or to the identification of possible anomalies through damage simulations. Finally, work developed internally for the optimisation of calculation processes is displayed in the last section, in particular, an Excel spreadsheet capable of speeding up the verification of the seismic safety of existing reinforced concrete buildings, according to the expedited methods I and II present in the LNEC, Sousa et al. report (2019).
