Structure: a two-family building located in Ozzano dell’Emilia BO consisting of 2 above-ground floors and a basement floor with masonry load-bearing structure, floors and roofing made of brick.
Foundations: the current foundation consists of a reinforced concrete perimeter beam and a central plinth on both portions of the duplex. The east portion of the duplex was partially piled during 2020. The west body, at the north front l front, has a building potion with a reinforced concrete wall against the ground that has no deepening beyond the p.c.
Failure: the lesion lattice (single- and multiple-branch inclined, sub-horizontal and sub-vertical) produced by shear and bending stresses corresponding to asymmetrical deformations, shows shear-flexure type ruptures with phase of detachment motion, with relative type of motion, and classifies the failures as relative terminal differential vertical translations of the east body in the north, northeast direction.
Soils: from the investigations provided by the client, soils with varying toe strengths are present at the site up to a depth of about 11 m from the basement where there is a layer of compacted soil. Clay soils are subject to volumetric shrinkage and contraction phenomena due to drying of surface lithotypes and subsequent swelling as a result of seasonal climatic and rainfall patterns. These phenomena are accentuated in the dewatering action exerted by the suction of tree roots in the vicinity of the building, in leaks or dispersions of water or sewage systems, and in the inadequate regulation of downspout drainage water; for the above-mentioned phenomenologies, careful verification and eventual, prompt restoration are recommended.
