Worked Examples To Eurocode 2 - Volume 2

Eurocode 2 Volume 2 (formally EN 1992-2) provides specific rules for the design and detailing of concrete bridges. Because this code acts as an extension of the general rules found in Part 1-1, worked examples often focus on the bridge-specific modifications to those baseline rules.

Sample Worked Example (Chapter 6 – Crack Control)

She pulled out a notepad and began sketching. "Eurocode 2 gives us the rules, but Volume 2 shows us how to break them safely. Look here—they calculate crack widths for a curved retaining wall with variable curvature. The principle is the same: we find the critical tensile zone, limit the steel stress using Equation 7.9, and check the crack width with 7.8."

Worked Example 2: Torsion + Shear in a Spandrel Beam

Scenario: L-shaped spandrel beam, 300 mm wide × 600 mm deep. worked examples to eurocode 2 volume 2

Step 5: Torsion link reinforcement

[ \fracA_sws = \fracT_Ed2 A_k f_ywd \cot\theta = \frac45e62 \times 105,306 \times (500/1.15) \times 2.5 ] ( f_ywd = 435 \text MPa ) [ \fracA_sws = \frac45e62 \times 105,306 \times 435 \times 2.5 = \frac45e6228.9e6 \approx 0.197 \text mm^2/\textmm ] For 2 legs (torsion acts on all walls) → per leg: ( A_sw/s = 0.098 ) Use ( \varnothing 10 ) (78.5 mm²) → spacing ( s = 78.5 / 0.098 \approx 800 \text mm ) – too large; torsion rarely governs spacing; shear likely demands tighter.
