The present study investigates and advances on existing research on the structural performance of box-celled composite structures for its use as a wind-resistant roof system.The box-celled panel system is produced by casting ultra-high performance fibre-reinforced concrete (UHPFRC) into galvanised steel roofing profiled sheets with anchor screws and expanded polystyrene foam (EPS) placed in-situ to produce a light-weight system.Three reinforcement-based variations of Shower Shelf the design are investigated and two panels for each variation are cast to produce six specimens.The structural responses of the variations as one-way panels under three-point flexure are experimentally studied for both positive and negative bending moment capacities.

Test specimens showed flexural failure with significantly ductility and post-failure load capacity, and anchor screws preventing full delamination of steel profile and shear failure.Analysis based on the test results confirmed that the proposed system is Outdoor Games - Games compliant to various design standards based on upper limits for combined loading actions, and permissible deflections, highlighting its optimal performance.
