Digital Survey and Algorithmic Modeling in Hbim. Towards a Library of Complex Construction Elements

Abstract

<p><strong>Abstract.</strong> In the study of built heritage, the introduction of BIM models provides the advantage of a set of data that can be shared between different platforms. Despite the continuous progress in research, the modeling processes of complex construction elements, typical of historical architectures, always require a certain attention and care that involve considerable investments in terms of both resources and time. In this paper we present the first results of an ongoing research aimed at considering possible methods that can allow a simplification of the modeling processes of elements of historical architectures in the BIM environment. In particular, the research aims to explore the possibilities offered by the algorithmic modeling of complex construction elements. In the study of historical architecture, an enough recurring theme concerns those elements that can be traced back to the principles of architectural orders. In the survey of historical architecture, a quite recurring case study concerns those elements or parts of building ruled by the principles of architectural orders. One of the first elements taken into consideration was that of the column that, in its articulation in base, shaft and capital, offers three different levels of complexity of the modeling process very suitable for the research path. Starting with a collection of data acquired from digital photogrammetric modeling, we considered a initial set of different case studies that allowed us to conduct a first working hypothesis by embracing a quite wide range of possible variations starting from a basic column.</p>

Parametric HBIM Procedure for the Structural Evaluation of Heritage Masonry Buildings

“…In parametric design, the informed model is able to perform actions and achieve objectives only through the use of mathematical algorithms. Obviously, the higher the interoperability between BIM software and algorithmic design software is, the easier the data management in the cognition and assessment stages [46][47][48].…”

“…Considering that, in parametric design, algorithms are defined to control the parameters from which elements can be generated, parametric object modeling provides a powerful way to both create and analyze models using mathematical algorithms. The advantages of the algorithmic approach mainly relate to increased control of the information [46][47][48], which allows easy extrapolation and management of any data from the model. Thus, by means of interoperability between BIM software and algorithmic design software, it is possible to develop procedures that perform customized analyses of the model using element parameters as input data.…”

Remote Practice Methods of Survey Education for HBIM in the Post-Pandemic Era: Case Study of Kuiwen Pavilion in the Temple of Confucius (Qufu, China)

“…So Li et al (2019) [4] continued to suggest that the fundamental issue of HBIM is the balance between regularization modeling and differentiation modeling. Therefore, the algorithmic modeling of HBIM could be a better solution because it is easy to repeat with node-visible modeling programs [5][6][7][8][9][10].…”

Virtual Environments to Communicate Built Cultural Heritage: A Hbim Based Virtual Tour

“…On the other hand, vaults and column shafts, belonging to categories of elements that have already been the subject of research in the past on the use of algorithmic modelling tools applied to complex historical elements, have been generated according to this methodology Bagnolo et al, 2019). The capitals of the columns finally fall into a category that requires a different approach; they, in fact, are geometrically very complex elements, whose parametric modelling is possible but extremely expensive in terms of time and resources.…”
