“Temperature-strain coefficient” for analyzing mechanical behaviors of stone-structures

Abstract

In this study, “stone-wall bulging index” and “temperature-strain coefficient” for analyzing mechanical behaviors of stone-structures are described. “stone-wall bulging index” is defined as a ratio (bulging(cm)/bulging height(m)) of a stone-wall. A relation of strain change for temperature change under a external force uniformly condition is defined as “temperature-strain coefficient”. Two cases of modern age castle masonry wall and one case of arch-type stone bridge were conducted with strain measurements. As the results, “stone-wall bulging index” and “temperature-strain coefficient” in these three cases of strain measurement can be useful for analyzing mechanical behaviors of other modern age castle masonry walls.
