TS500 Balanced Reinforcement Ratio
ρ = Tensile reinforcement ratio in beam
ρ b = Balanced reinforcement ratio inbeam
ρ ' = Compressive reinforcement ratio inbeam
ρ max = Maximum reinforcement ratio in beam
TS 500 Article 0.2.5 - Balanced Reinforcement Ratio
Balanced reinforcement ratio is the reinforcement ratio that provides the bearing strength of a reinforced concrete beam under bending by the flow of the tensile reinforcement and the crushing of the concrete in the outermost compression fiber at the same time.
Article 7.3 of TS 500 - REQUIREMENTS REGARDING THE DIMENSIONS AND FITTINGS OF BENDING ELEMENTS
Tensile reinforcement ratio ρ in beams cannot be less than the following value.
