Empirical Cellular Automata Model to Predict Failure Patterns of Laterally Loaded Masonry Wall Panel

Abstract:

This paper proposed an empirical relative variation coefficient to improve performance of cellular automata model which was put forward by Zhou^[1] to predict failure patterns of masonry wall panels under lateral load. The improved empirical cellular automata model could take discreteness of failure patterns into account. Then, parameter analysis of the empirical variation coefficient was conducted to find out its reasonable value interval. Consequently, a serial failure patterns could be predicted on the basis of each experimental record. A comparison between predicted failure patterns and experimental results has been made, which proved the empirical cellular model with relative variation coefficient was not only one-to-multiple, but also valid.
