Abstract

A mockup representing a historic masonry vault was tested on the shaking table and finally brought to collapse. During the seismic test, a video was taken and then processed by the motion magnification algorithm to magnify the smallest displacements. Subsequently, each frame of the video was translated into a graph to be analyzed by means of the graph theory centrality measures. Some graph standard parameters showed a significant variation in their value along the video frames before collapse. Therefore, such parameters showed the potential to predict the collapse of the structure.
