Worked Examples To Eurocode 2 Volume 2

Actual ( \lambda = 57.7 ), ( \lambda_lim = 58.1 ) → Second-order effects may be ignored (just satisfied).

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.

While Volume 1 explains how to size a beam, Volume 2 explains how a building stands up, resists fire, accommodates movement, and interacts with the ground.

A critical nuance: Worked Examples to Eurocode 2 Volume 2 often uses UK National Annex parameters (e.g., $\alpha_cc = 0.85$, $\gamma_c = 1.5$). However, the methodology is universal.

The volume includes a separate table showing how the output changes if you adopt:

Pro tip: When using these examples, always overlay your country’s National Annex coefficients.

No resource is perfect. Volume 2 has two notable limitations:

Additionally, some examples assume proprietary software for analysis (e.g., for bridge moving loads). This is acceptable, but the book should have included a manual influence line check.

The Scenario: A 2m thick pile cap transferring 10,000 kN from a column to four piles. The span-to-depth ratio is less than 2, invalidating Bernoulli beam theory.

Key Eurocode 2 Clauses applied: 6.5 (Strut-and-tie method). worked examples to eurocode 2 volume 2

Why this example is revolutionary: Most engineers fear strut-and-tie (STM), but Volume 2 demystifies it. The example shows how to model a D-region (discontinuity region) using a truss analogy.

The Worked Solution Highlights:

Takeaway: Volume 2 provides a fully resolved STM with actual bar bending schedules—not just force diagrams.
