The slab had suffered severe damage and cracking due to poor concrete casting, as well as thermal cracking. There was also the additional need to increase the gravity loads that the slab could support. Initially, static analyses with 2D finite elements were conducted, in order to confirm the cause of the cracking, by matching the stresses diagram of the model against the real cracks distribution. Subsequently, retrofit and strengthening interventions for the slab were proposed: sealing the cracks with resin injections and strengthening in bending with FRP laminates.<\/p>\n<p>The study was carried out in late 2020.<\/p>\n<\/div><div class=\"fusion-image-carousel fusion-image-carousel-fixed fusion-image-carousel-1 lightbox-enabled fusion-carousel-border\"><div class=\"awb-carousel
