Composite Slab Construction Requirements

Bearing Requirements

Composite slabs bearing on steel or concrete should normally have an end bearing of not less than 50 mm. For composite slabs bearing on other materials, the end bearing should not be less than 70 mm.

At intermediate supports of continuous slabs the bearing length should not be less than 75 mm on steel or concrete and 100 mm on other materials.

Nominal Reinforcement At Intermediate Supports

The composite slab is designed as simply supported. Where the slab is continuous over intermediate supports and the exposure condition is mild anti-crack reinforcement with a minimum area of 99 mm²/m is required along the line of support.

For other exposure conditions reference should be made to BS 8110.

Transverse Reinforcement

Steel mesh reinforcement with a minimum area of 70 mm²/m is required transverse to the span of the slab.
