Interactive software for mapping concentrated displacements in masonry arches

Arches are an important part of the masonry architectural heritage and also serve as infrastructure for bridges culverts. The behavior testing structural health monitoring arches require effective measurement methods. There have been a lot methods applied regarding this subject, among which vision-based non-destructive very appealing. However, demands measuring accuracy range increase, labor economic costs expand to uneconomical levels. A novel, cheap, fast strategy focuses directly on mechanical failure has developed. This termed Behavior Mapping (BM) is based homography does not high-precision camera or extensive experimental setup. scale dry-stack arch was subjected repeated collapses through springing displacements during proof-of-concept development BM. generated huge amount data required MATLAB® graphical user interface (GUI). objective article introduce GUI accompanying purpose providing educational insight into arches. These cases integrated in provide possibility better understand mechanism dry-stone under foot displacement, well easily identify occurrence joints determine value deformations. can be adapted different configurations, further real-time monitoring.
