15.7. SHAPE CHANGING LIMITS
15.7.1. Section Deformation and Plastic Rotation Limits of Reinforced Concrete and Pre-fabricated Reinforced Concrete Elements
22.214.171.124 - Unit deformation demands of concrete and reinforcement steel obtained according to 15.5.4 or 15.6.2 will be compared with the unit deformation capacities defined below, and the performance of the carrier system at the cross-section level will be determined.
126.96.36.199 - If the longitudinal reinforcements of the reinforced concrete elements whose shape deformation is calculated are arranged with un-ribbed (flat) reinforcing steel, the unit deformation demand of the reinforcing steel and the demand for plastic rotation will be increased by multiplying by 1.5.
188.8.131.52 - Permissible unit strain and plastic rotation upper limits (capacities) according to various section damage limits in reinforced concrete ductile beam, curtain and column elements where plastic deformations occur 184.108.40.206 , 220.127.116.11 , 18.104.22.168 and 22.214.171.124 ' well defined. In the calculation of ρ sh in Eq. (5.4d) , 30% of 90 degree closed stirrups can be taken into account. In Equation (5.6) given in 126.96.36.199 , L s shall not be taken less than L p .
188.8.131.52 - If the shear force ratio V e / (b w d f ctm ) of the reinforced concrete section for which deformation is calculated is <0.65, the upper limits of deformation calculated according to 184.108.40.206 are valid. If the shear force ratio is greater than 1.30 , the deformation upper limits calculated according to 220.127.116.11 will be reduced by multiplying by 0.50. Linear interpolation will be applied for intermediate values.
