The paper introduces an intelligent method to analyze the behaviours of the laterally loaded masonry panels with openings directly based on the existing experiments. In comparison with the results from the finite-element analysis (FEA) of the “base” panel with the experimental results, local property coefficient are used to describe the variability of different zones within the base panel. Using the cellular automata (CA) technique, numerical models are established to calculate the zone state values both in the base and unseen panels. Then according to the state values, similar zones, which have the same local property coefficient, are matched by the matching criterion. The initial elastic modulus of the unseen panels is multiplied by the local property coefficients and applied in the improved FEA to predict the behaviours of unseen panels. The results indicate that this method is effective for analyzing the deformation of the masonry panels with openings.
