Design　codes　provide　requirements　for　traditional　slabs　to　ensure　both　safety　levels　and　in-service　functionality　criteria.　However,　for　existing　structures,　an　initial　diagnostic　knowledge　phase　is　essential　to　characterize　the　actual　health　state,　e.g.　based　on　structural　health　monitoring　(SHM)　with　operational　modal　analysis　(OMA)　techniques.　Considering　recent　advancements　in　glass　as　a　structural　material,　laminated　glass　(LG)　slabs　are　increasingly　used　in　constructions　and　are　mostly　designed　to　account　for　the　intrinsic　brittleness　and　limited　tensile　resistance　of　glass.　The　latest　pre-code　CEN/TS　19100:2021　is　paving　the　road　for　an　imminent　future　Eurocode　10　dedicated　to　providing　new　standards　for　the　innovative　use　of　structural　glass.　In　the　current　study,　a　brief　review　of　the　design　challenges　of　working　with　structural　glass　is　presented.　After　that,　the　authors　provided　a　simple　experimental　dynamic　identification　example　of　an　LG　pedestrian　walkway　located　in　the　Basilica　of　Aquileia,　Trieste　(Italy).　Specifically,　the　fundamental　mode　was　compared　to　a　healthy　and　a　partially　fractured　LG　slab.　Functionality　aspects　related　to　comfort　standards　with　respect　to　in-service　vibration　issues　are　also　detailed.　©　2023　Ernst　&　Sohn　GmbH.
