Abstract(s)
A evolução da sociedade humana está, em parte, relacionada com a evolução das tecnologias.
O desenvolvimento das tecnologias de informação, especialmente dos softwares, que facilitam
os trabalhos humanos faz com que toda uma sociedade caminhe para um desenvolvimento
tecnológico mais amplo.
Nesse contexto, o setor da arquitetura, engenharia e construção (AEC) também têm necessidade
de buscar inovações que tragam melhorias para a humanidade e redução de tempo e de custo
nas tarefas necessárias à execução de um empreendimento. Estes foram alguns intuitos que
levaram ao surgimento e implementação da metodologia BIM – Building Information Modeling
– um pouco por todo o mundo.
O presente estudo tem como principal objetivo a aplicação da metodologia BIM no
desenvolvimento de um projeto de estruturas de um edifício multifamiliar em betão armado.
Inicialmente criaram-se os modelos BIM de arquitetura e de estruturas, através da utilização do
software Revit, tendo-se concebido duas soluções estruturais distintas. Para analisar o graus de
interoperabilidade, isto é a quantidade e qualidade da informação transferida, entre o Revit e os
softwares de análise estrutural utilizados neste trabalho (Robot Strucutural Analysis, TQS
Estruturas e Eberick) foram utilizadas as duas soluções estruturais concebidas, com diferentes
tipos de ações, de acordo com as regulamentações em vigor em Portugal (Eurocódigos) e no
Brasil (NBR). Esta interoperabilidade foi avaliada através dos fluxos de transferência nos dois
sentidos, ou seja, do Revit para o software de análise estrutural e deste novamente para o Revit,
tendo-se procurado sistematizar as melhores práticas para cada um dos softwares adotados.
O estudo é complementado com uma análise comparativa das várias soluções estruturais obtidas
para as diferentes condições e regulamentações, utilizando-se para o efeito o mapa de
quantidades de materiais obtido para cada solução.
Os resultados encontrados, apesar das limitações identificadas ao longo do processo,
essencialmente devidas a problemas de interoperabilidade, indicam uma facilidade no processo
de modelação comparativamente com a metodologia tradicional de trabalho, mostrando as
vantagens evidentes no desenvolvimento do projeto, nomeadamente na capacidade de
concentração da informação, na sobreposição das especialidades e na avaliação de diferentes
soluções, identificando qual a solução mais viável economicamente, mas ainda carecem de
melhorias na troca de informações referente ao detalhe das armaduras.
ABSTRACT: The evolution of human society is partly related to the evolution of technologies. The development of information technology, especially software, which makes human jobs easier, makes the whole of society move towards wider technological development. In this context, the architecture, engineering and construction (AEC) sector also needs to seek innovations that bring improvements to mankind and reduce the time and cost of the tasks required to execute a project. These were some of the purposes that led to the emergence and implementation, around the world, of BIM - Building Information Modeling. This study has as main objective the application of BIM in the development of a structural design of a reinforced concrete building. Initially, the BIM models of architecture and structures were created, through the use of Revit software, and two different structural solutions were designed. To analyse the degree of interoperability, i.e. the quantity and quality of information transferred, between Revit and the structural analysis software used in this work (Robot Strucutural Analysis, TQS Structures and Eberick) were used the two structural solutions designed, with different types of actions, according to the regulations in force in Portugal (Eurocodes) and Brazil (NBR). This interoperability was evaluated through the transfer flows in both directions, i.e., from Revit to the structural analysis software and from this again to Revit, having sought to systematize the best practices for each of the adopted software. The study is complemented with a comparative analysis of the various structural solutions obtained for the different conditions and regulations, using the map of quantities of materials obtained for each solution. The results found, despite the limitations identified throughout the process, essentially due to interoperability problems, indicate an ease in the modelling process in comparison with the traditional work methodology, showing the evident advantages in the development of the project, namely in the ability to concentrate information, in the overlapping of specialities and in the evaluation of different solutions, identifying the most economically viable solution, but still lacking improvements in the exchange of information regarding the reinforcement detail.
