# Minimum area of surface reinforcement `A`_{s,surfmin}

_{s,surfmin}

## Eurocode 2 part 1-1: Design of concrete structures J.1 (2) - Annex J (informative)

The area of surface reinforcement `A _{s,surf}` should be not less than

`A`in the two directions parallel and orthogonal to the tension reinforcement in the beam.

_{s,surfmin}## Recommendation

The recommended value of the reinforcement area `A _{s,surfmin}` is 0,01

`A`, where

_{ct,ext}`A`is the area of the tensile concrete external to the links (cf. Figure J.1).
