Masonry bridges are usually considered as an arch to which non-structural elements (spandrels, fill, etc.) are added. Experimental and theoretical evidences show, instead, that spandrels and fill take part in the load carrying mechanism accounting for a large part of the load carrying capacity. If this is neglected, the structural models may turn out to be unreliable and their outcomes strongly non-correlated with the real response of the bridge. In this paper, the arch-fil and arch-spanrel interaction is demonstrated and quantified by means of experimental tests on reduced scale models set on proper scaling rules.

Abstract

Masonry bridges are usually considered as an arch to which non-structural elements (spandrels, fill, etc.) are added. Experimental and theoretical evidences show, instead, that spandrels and fill take part in the load carrying mechanism accounting for a large part of the load carrying capacity. If this is neglected, the structural models may turn out to be unreliable and their outcomes strongly non-correlated with the real response of the bridge. In this paper, the arch-fil and arch-spanrel interaction is demonstrated and quantified by means of experimental tests on reduced scale models set on proper scaling rules. Woth deep and shallow arches are considered.
