Eurocode 2 (EN 1992) represents the European standard for the design of concrete structures. While the code provides a comprehensive framework for safety, serviceability, and durability, its application requires a deep understanding of partial safety factors, load combinations, and intricate calculation procedures.
Worked Examples to Eurocode 2: Volume 2 aims to demystify these requirements through practical calculation routines. The purpose of this report is to evaluate the structure, content accuracy, and usability of the document for structural engineers and students. worked examples to eurocode 2 volume 2
Problem: A 300mm thick retaining wall is cast against a stiff raft foundation. The wall is 15m long with no movement joints. Calculate the crack width due to early-age thermal contraction.
Given: Concrete C35/45, Steel B500B, Restraint factor $R=0.7$, Temperature drop $\Delta T = -25^\circ C$, $\alpha_ct = 1.0 \times 10^-5$.
Step-by-step solution:
The Scenario: A 15m simply supported slab bridge, width 10m, subjected to LM1 (Load Model 1) traffic loads and thermal actions.
Key Eurocode 2 Clauses applied: 6.2 (Shear), 7.2 (Stress limitations), 7.3 (Crack control).
Why this example is critical: Volume 2 emphasizes that bridges are fatigue-critical. Unlike buildings, a bridge’s tensile stress limit under frequent loads (cl. 7.2(3)) often dictates reinforcement, not the ultimate moment. [ \lambda_lim = \frac20 \cdot A \cdot B \cdot C\sqrtn ]
The Worked Solution Highlights:
Takeaway: Volume 2 forces you to check serviceability before ultimate, reversing the typical building design order.
Since "Volume 2" is a functional description rather than a single universal title, look for these specific publications: [ \lambda_lim = \frac20 \times 1 \times 1
This report provides a critical review of Worked Examples to Eurocode 2: Volume 2. The document serves as a practical companion to EN 1992-1-1 (General Rules and Rules for Buildings), bridging the gap between theoretical code requirements and practical application. The volume is assessed as a high-value educational and professional resource, particularly regarding its systematic approach to reinforced concrete design. However, the report highlights the necessity for users to cross-reference the latest UK National Annex amendments and recent amendments to the Eurocode itself.
