f ck = Concrete characteristic compressive strength
f co = Compressive strength of unwrapped concrete
f yk = Characteristic yield strength ofreinforcement steel
f sy = yield strength of reinforcement steel
...
The element capacities are found by the moment-curvature relationship created by using material models found with the stress-strain relations of concrete and reinforcement steel .
Available material strengths are the characteristic of the material or the strength obtained from samples taken from the building. This characteristic compressive strength is called f ck for concrete and the characteristic yield strength f yk for reinforcement .
...
After the concrete compressive strength f co and reinforcement yield strength f sy values are found by using the current material strengths and information level coefficient ( Beton ve Donatı Çeliği için Gerilme-Şekildeğiştirme Bağıntıları Stress-Strain Curves for Concrete and Reinforcement Materials ), the material stress-unit deformation relations are created. The following picture shows the stress strain graphs of concrete and reinforcing steel, respectively.
