Abstract

The ultimate load carrying capacity of soil-filled masonry arches is significantly higher than that of bare masonry arches. The soil fill has a stabilizing effect on the masonry arch, distributing the live load and providing passive resistance to deformation of the arch. The masonry arch behaves in a discontinuous manner, governed by interaction between masonry units and soil-masonry interfaces, where forces and displacements are concentrated. In order to understand the behaviour of this soil-structure system, a full scale masonry arch was constructed under laboratory conditions within a stiff, very low-friction chamber to accommodate backfill and confine the system to planar deformation. The system was subjected to monotonic quasi-static loading to collapse. The experimentally observed behaviour is compared with that of a 2-dimensional numerical model of the system using commercial distinct element software.
