A atual mudança global imposta ao setor AEC – Arquitetura, Engenharia e Construção, em resultado da utilização cada vez mais generalizada de modelos paramétricos no projeto e na execução de estruturas de engenharia civil, exige uma maior especialização dos intervenientes na área da utilização de ferramentas informáticas, sobretudo num momento em que se reconhece as potencialidades da utilização da metodologia BIM (Building Information Modelling). Embora os profissionais disponham já de um conjunto consolidado de aplicações informáticas que resolvem com eficiência diversos problemas, nem sempre essa resposta é transversal ou aplicável a questões de projeto mais específicas, motivo pelo qual é ainda muito frequente a necessidade de desenvolvimento de personalizações e de extensões ou plug-ins dessas mesmas aplicações. O presente trabalho, desenvolvido no âmbito do protocolo estabelecido entre o DEC-ISEP e o Gabinete de Estruturas e Geotecnia – GEG, é dedicado ao desenvolvimento de ferramentas de automação da modelação BIM em elementos de betão armado. Incui a modelação tridimensional por elementos finitos e dimensionamento de armaduras do emboquilhamento de um túnel, a análise das ferramentas disponíveis para a modelação e a pormenorização de armaduras, e, finalmente, o desenvolvimento de um algoritmo específico para a modelação das armaduras de um caso de estudo. O algoritmo desenvolvido para a modelação das armaduras, que recorre à interoperabilidade entre ferramentas informáticas com um elevado grau de automatização, apresenta precisão satisfatória mesmo quando aplicado a estruturas mais complexas, contribuindo assim para a promoção da metodologia BIM no projeto de estruturas de betão armado.
The current global change imposed on the AEC sector - Architecture, Engineering and Construction, as a result of the increasingly widespread use of parametric models in the design and execution of civil engineering structures, requires greater specialization of the players in the making use of computer tools, especially at a time when the potential of using the BIM (Building Information Modeling) methodology is recognized and established. Although professionals already have a consolidated set of computer applications that efficiently solve several problems, the software outputs are not always transversal or applicable enough to more specific design questions, a reason for the current need to develop customizations and extensions of those same applications. In the present work, in a protocol between DEC-ISEP and Gabinete de Estruturas e Geotecnia - GEG, were studied tunnel design methodologies and was investigated the development of an automation tool for BIM modelling of beam reinforcements. Initially, three-dimensional modelling and determination of the need for reinforcement was performed using computer-aided calculation in a program based on the Finite Element Method (FEM). Subsequently, tools for modelling and detailing were investigated, and algorithms for reinforcement modelling automation were developed. The tools used to determine the desired project production process were compiled, a case study was elaborated and the advantages, disadvantages, boundary conditions and potential improvements of the process were discussed. The developed model, which uses interoperability between computer tools with a high degree of automation, presents satisfactory precision even when applied to more complex structures, thus contributing to the promotion of the BIM methodology in the design of reinforced concrete structures.
