That campaign produced an initial <a href=\"https:\/\/teknoprogettisrl.it\/en\/analysis\/\" target=\"_blank\" rel=\"noopener\">seismic vulnerability assessment<\/a>, capturing the building&#8217;s as-is condition and identifying the main critical issues. <\/p><p>Eight years later, in February 2022, that assessment was supplemented with new <a href=\"https:\/\/teknoprogettisrl.it\/servizi\/settore-controlli-non-distruttivi\/\" target=\"_blank\" rel=\"noopener\">penetrometric tests on the mortar<\/a> and an update of the numerical model, needed to refine the mechanical characterisation of the materials. The resulting picture was clear: the building \u2014 a load-bearing masonry complex in solid brick and lime mortar, with hollow-clay-and-concrete floor slabs and a timber roof, spread over two storeys above ground \u2014 showed significant seismic vulnerability. <\/p><p>The calculated iPGA (\u03b6E) parameter is <strong>0.41<\/strong>, with a PAM risk class of level G and an IS-V class of level F, referring to the masonry, identified as the critical element of the entire building. Access to PNRR funds offered the opportunity to turn diagnosis into action.

href=\"https:\/\/teknoprogettisrl.it\/en\/services\/structural-specialty-design\/\" target=\"_blank\" rel=\"noopener\">seismic improvement project<\/a> is structured around four main categories of intervention, each designed to address a specific structural weakness.<\/p><p><strong>Strengthening of the masonry piers. <\/strong>This is carried out by strengthening with an FRCM (Fibre Reinforced Cementitious Matrix) system: a balanced biaxial mesh in basalt fibre and AISI 304 stainless steel, embedded in two layers of NHL 3.5 lime-based geomortar, applied to single or double wall faces on the raised ground floor and the first floor. Before application, the surfaces are prepared by removing the existing plaster and repointing the joints; the fabric is anchored to the masonry with 8 mm AISI 316 stainless-steel helical bars, certified to EN 845-1. <\/p><p><strong>Top ring beams. <\/strong>These are created by strengthening with strips of ultra-high-tensile galvanised steel fabric (UHTSS), laid at the underside of the floor slab on both the raised-ground-floor roof deck and the first-floor one. The intervention creates a stiff ring at the top of the masonry, distributing loads evenly and reducing the risk of local overturning of the individual piers. <\/p><p><strong>Strengthening of the masonry columns. <\/strong>Confinement with strips of the same UHTSS fabric improves the ductility and strength of the columns supporting the roof&#8217;s load-bearing elements at the attic level.<\/p><p><strong>Replacement of the roof-truss tie rods. <\/strong>The existing tie rods are replaced with new S275 galvanised-steel ties \u2014 complete with 400\u00d7200\u00d78 mm anchor plates \u2014 eliminating the horizontal thrust transmitted from the roof to the masonry, one of the primary causes of vulnerability in historic buildings with timber
