“…Grasshopper-Archicad Live Connection tool enables the structural model to be analyzed using an appropriate algorithm with visual programming language (VPL). Grasshopper extracts all previously defined structural data, performing the additional user-specified codes required by the linear or nonlinear structural analyses [6][7][8][9][10][11], as well as the assessment of the structural performance under non-seismic and seismic actions. Combination of Archicad and Grasshopper allows for a highly organized and efficient working flow, where the following main phases can be identified:…”

“…The architectural model is used as a geometric reference for the structural model [10,11], based on the principles of the E-PUSH method [6,7]. The "wall" elements, previously created in the architectural model, are copied and converted into "morphs", distinguishing structural walls, non-structural walls and masonry spandrels, including lintels, while floors, roofs and stairs, that are converted into "shell".…”

“…Given these concerns, assessing the vulnerability of existing masonry buildings is crucial [6][7][8][9][10][11]. EN1998-3 [12] and also Annex B of the ISO13822 [13] provide general procedures for seismic evaluation and retrofitting of existing structures.…”

“…In the E-PUSH software, consisting of routines written and executed in the MATLAB environment [24], input data for the analysis of the investigated buildings are collected in a table, which can be compiled manually or by means of an Excel file, containing the geometric and mechanical properties of masonry walls, and the stresses due to vertical loads. Requiring a limited number of input data and being based on very clear and simple structural models, the E-PUSH program is nearly independent of the users, so that efficient workflows can be developed for the safety assessment of existing masonry buildings [6,7,[9][10][11].…”

“…In this study, the phases of the assessment of an existing masonry building are established and managed in an HBIM, or BIM, environment, where preliminary modeling of the building is the starting point of the information exchange process, allowing a practically unlimited and ongoing increase in the data required by the assessment process [10,11]. The original contribution aims to develop an informed model that can be used as a database for both the physical/architectural and the analytic/structural discipline, preserving all relevant information throughout the whole lifecycle of the construction.…”

In the architecture, engineering and construction sectors, Building Information Modeling (BIM)-based procedures have become adopted more and more. In fact, the development of suitable BIM models facilitates the management of the design and construction phases and improves the efficiency of the maintenance policies during the life cycle of the building. Although the BIM method is mostly implemented in the building industry for new constructions, in recent years, the deployment of this technology has also attracted increasing attention for existing structures to rebuild their geometry and gather relevant data, especially for historical buildings; in this case, we refer to Heritage BIM (HBIM). A HBIM procedure requires a multidisciplinary approach involving not only historical, conservation, and restoration considerations but also suitable maintenance and repair plans, duly balancing the structural needs with the preservation of the historical value of the building and its content. Although the integration of the structural assessment in the HBIM process would be highly beneficial, its practical implementation is often in the early stages. In the paper, an original parametric procedure for the assessment of existing masonry buildings is proposed in the BIM environment. The procedure combines E-PUSH, a software program for the structural analysis of masonry structures under seismic and non-seismic actions with an appropriate BIM approach, so improving the management of gathered data through cognitive phases. The assessment process is, thus, simplified since data required for the structural analysis are directly retrieved from the BIM model, and the structural analyses and verifications are performed without using external programs. The proposed BIM workflow is finally illustrated and discussed referring to a relevant case study, the seismic vulnerability assessment of the “Bernardo Rucellai” school in Florence (Italy).

The research deals with the issue of the seismic and energy retrofit of historic building fabrics having as reference a historic district of Syracuse (Italy). The prospect of the ecological transition on the one hand and the public support funding on the other claim for a valuation programming approach implying the creation of multiple scenarios, each of which is inspired by a different and complementary degree of “saliency and urgency”. These two dimensions of “being worth” by a building aggregation having an its own shape and belonging to a larger and more complex urban system need to be addressed according to some axiological reference, in this case, the concerns of the efficiency and fairness of public spending. This experience concerns the creation of a value-based programming pattern of the seismic–energy retrofit process framed in a Building Information Modelling (BIM) environment aimed at identifying the best intervention strategy among the several ones that can be generated in the logic of the parametric design. Both seismic and energy retrofit expected performances, in fact, can be scaled, complementing the extension and intensity of the interventions. This experiment takes advantage of the BIM multidimensional logic in line with the multiple scales and purposes implied by the relationships between individual/communal axiological profiles and present/future prospects. The experiment consists of the creation of an additive cost-oriented design platform based on which the different and progressive combinations of intensity and extension of the interventions can be compared and selected.
