GENERAL

1. Bond-lok floor slabs are basically one-way slabs designed to carry uniformly distributed loads. The tables do not cater for heavy concentrated loads or moving loads. Where these occur the design should be referred to a civil/structural engineer.
   
2. Calculations are generally in accordance with BS5950 Part 4 : 1984 (limit states design). Deflection during Construction calculated at span/180.
   
3. For normal applications of Bond-Lok steel floors. no additional reinforcing other than a light mesh for shrinkage control is required, typically 193 mesh.
   
4. For "Fire Applications" of Bond-Lok floors. welded steel mesh reinforcement of 8 mm diameter steel bars at 200 mm spacing in each direction is required, with minimum top cover along supports (typically on top of shear studs). This gives a fire rating of 90 minutes for a slab of 140 mm or greater with a nominal superimposed load of 2,5 kN/m2 maximum, for spans up to 3,0 m.

For further information on fire applications contact Brownbuilt. Material - minimum guaranteed yield stress 200 MPa.
N.B. All tabulated values serve as a guide only for single span conditions, and should be certified and approved by a civil/structural engineer.
