Abstract
This paper describes the implementation an Artificial Neural Network (ANN) surrogate model that predicts the wind-induced, vertical displacements of cable nets supporting hyperbolic paraboloid roofs. The ANN model was calibrated by training experimentally derived pressure coefficients of the hyperbolic paraboloid roofs with rectangular and square plan shape, obtained through parametrization of main geometric properties through polynomial fitting function. Pressure loads, found by aerodynamic tests, were used to calibrate the ANN model, which was subsequently employed to synthetically generate vertical displacements of a roof shape with varied geometry. Training was also refined using vertical displacements measured through aeroelastic wind tunnel tests, carried out on two geometries with a square roof plan and two with a rectangular roof plan.
