A parametric model for ribbed masonry vaults
https://orcid.org/0000-0001-5300-3932
Abstract The paper presents a new method aimed at the automated modelling of ribbed masonry vaults, based on parametric modelling integrated with measurements and in-situ observations. The procedure starts with direct observation in-situ which provide information for construction rules, geometry and connection between different structural elements. Important geometric data for individual vault elements such as arch, rib and web are obtained from the elaboration of point-cloud measurements. These data are used as inputs into a parametric model, created to generate automatically the three-dimensional geometry with solid elements. The final assembly includes individual members (arch, rib, web, rubble-fill) and nodal zones (tas-de-charge). The model is used for three-dimensional numerical finite element analysis, to study the structural response. Moreover, the same model can be used in a Building Information Modelling environment. Results show that different ribbed masonry vaults such as quadripartite (with square, rectangular, or trapezoidal shape in plan) or sexpartite can be generated just by changing the input parameters of the parametric model.
Highlights The parametric model has been successfully applied for automatic modelling of ribbed masonry vaults with solid geometry. Inputs necessary for the geometric modelling are extracted from the point cloud measurements and direct in-situ observation. Different kinds of ribbed masonry vaults can be generated by the same parametric model. Possibility of generating very complex simulation models, with respect to the current state of the art. The developed refined simulation models can be used to better approximate the structural behaviour of ribbed masonry vaults.
