Design a reinforced concrete column to Eurocode 2

Describe the column to Mia in your own words. Height, cross-section, concrete class and the design forces at the ends are enough to start. She classifies the slenderness, applies second-order effects using the nominal curvature method and designs the required longitudinal reinforcement for you. The result is a complete EN 1992-1-1 verification with transparent formulas, assumptions and detailing checks, ready to download as a PDF report.

Що перевіряє цей Skill

Slenderness and second-order effects

Classifies slenderness per EN 1992-1-1 §5.8.3 and applies the nominal curvature method §5.8.8 when λ exceeds λ_lim.

Cross-section reinforcement design

Determines required symmetric reinforcement A_s,req using the rectangular stress block of §3.1.7 by iteration or design-chart approach.

Detailing checks per §9.5

Verifies A_s,min and A_s,max limits, minimum bar diameter, and transverse reinforcement spacing against EN 1992-1-1 §9.5.

Practical bar arrangement proposal

Proposes a reinforcement layout (e.g. 4 Ø20 + links Ø8/300) satisfying both the required area and the detailing rules.
