Assessing the safety of vaulted masonry structures using thrust network analysis

• TNA assessment of masonry vaults by solving nonlinear constrained optimisations. A direct optimisation to find the minimum thickness, and GSF, vaults. Robustness vaulted structures through stability domain analyses. numerical approach for with geometry from point clouds. new SDV-based interactive algorithm select independent force densities. This paper presents a methodology assess using Thrust Network Analysis (TNA). It offers strategy compute Geometric Safety Factor (GSF) given structure directly evaluating its thickness. Moreover, it provides an tracing vault’s based on extreme thrust values, which indicates robustness structure. Together, these outcomes represent proper measure safety level structures. Such results are obtained problems (NLPs) appropriate objective functions constraints enforcing limit analysis’ admissibility criteria. Networks fixed horizontal projection considered, spatial is function densities height support vertices. faster, procedure proposed improve selection such The range applications present method includes arbitrary network topologies different conditions. Beyond analytically described geometries, can deal geometries numerically (e.g. clouds). presented implemented in Python-based package, relevant illustrate method’s potential assessing three-dimensional historic
