... (supervised machine learning) using a neural network (NN) (NN) a (2) physics-based method using the matrix update method. Findings Results show the outputs are well correlated in both methods, and the results are matched with observed damage in low and intermediate seismic level stages. On the other hand...

... the active subspace theory and neural network. Design/methodology/approach This study aims to improve the efficiency of global sensitivity analysis for high-dimensional structural systems, a novel method based on active subspace and surrogate model is proposed. Active subspace can reduce the dimension...
