ABSTRACT

Currently, tangible heritage has been affected by lack of maintenance, human interventions and deterioration due to natural causes, which is why research aimed at the conservation of heritage assets that preserve the history, tradition and identity of a place is required. The current study is performed in order to apply modern methodologies in a heritage asset, starting from a Historic Building Information Modeling (HBIM) model of architectural documentation to conduct its structural evaluation in a non-linear finite element analysis software. The proposed workflow begins with collecting information with a 3D laser scanner. The processing, debugging and management of data is realized in the Trimble Real Works software, then the model is exported to the HBIM ArchiCAD 24 software, where the building can be seen in 3D. This is how the detail plans in plan and elevation are generated, of which the model is exported to allow the structural evaluation to a software for finite element analysis DIANA FEA (acronym for Displacement Analyzer). Using a three-dimensional geometric model, a pushover analysis is performed, which allows data to be obtained on the most critical or vulnerable elements that would be affected in the event of a seismic movement. The results of this evaluation are of relevant importance in the case of the Balbanera church, since they constitute a basis, from which an intervention project can be proposed considering the current requirements of the structure. In addition, the HBIM model offers the facility of multipurpose, that is, one is able to work on several topics included in the same 3D model. The proposed methodology could become a standard model for studies in other heritage buildings.
