\( N_{Rd} = \frac{A_c \cdot f_{ck} + A_s \cdot f_{y}}{\gamma_c} \)
Glossary of Variables
- \( A_c \): Cross-sectional area of the concrete (m²).
- \( A_s \): Cross-sectional area of the steel (m²).
- \( f_{ck} \): Characteristic cylinder compressive strength of the concrete (N/mm²).
- \( f_{y} \): Yield strength of the steel (N/mm²).
- \( \gamma_c \): Partial safety factor for concrete.
- \( N_{Rd} \): Design resistance (N).
How it Works: A Step-by-Step Example
Consider a composite column with the following parameters: \( A_c = 0.02 \, m² \), \( A_s = 0.003 \, m² \), \( f_{ck} = 30 \, N/mm² \), \( f_{y} = 355 \, N/mm² \), and \( \gamma_c = 1.5 \). Plug these values into the formula to calculate the design resistance.
