Abstract:

This study investigates the deflection behaviour of Bubble Deck slabs using numerical and experimental approaches. Two techniques - numerical homogenization and 3D cross-sectional integration - are applied to derive equivalent properties for simplified finite element models. A scaled slab specimen (1020×2040×60 mm) with a reinforcement mesh of ?4 bars spaced at 30 mm (top and bottom) and plastic spheres (?40 mm, spaced at 60 mm) is tested under self-weight and a mid-span linear load. The slab, simply supported on two shorter edges, is modelled both in full 3D and using simplified 2D model with homogenized parameters. Experimental deflections are compared with numerical and analytical/theoretical predictions to validate the proposed techniques, demonstrating their effectiveness in simplifying structural analyses while maintaining accuracy.
