Hoesch Additive Floor

The calculation and structural detailing of a Hoesch Additive Floor (HAF) in a carpark building is considered. The floor resistance is obtained by summing resistances of profiled steel sheet and ribbed reinforced concrete slab without composite action. Referring to EN 1994, the system is a combination of two materials, steel and concrete, with the degree of shear connection η = 0. The calculation is conducted using EN 1994‐1‐1 and Technical Approval. The bending moment is carried by the profiled sheet and the reinforced concrete ribbed slab. Their load‐bearing capacities can be added. The bearing of shear force is provided at the supports via the profiled sheet and the patented cleat support. Bending moment is carried by both the trapezoidal sheet and the RC ribbed slab.
