A two-bay test panel from a Primekss PrimX steel-fibre-reinforced
concrete industrial floor system. The slab was instrumented with
distributed fibre optic sensors during construction. Three static
load tests were performed at the east, centre, and west of the
panel using IBC water tanks to apply a 10 kN/m² uniformly
distributed load on the slab surface. Click any fibre line to
inspect its strain trace, or toggle the 2D strain heatmap to see
how the floor responds under each load.
