Ciria C577 -

If you design buildings, manage risk, or construct multi-storey structures, understanding CIRIA C577 isn’t optional—it’s critical.

❌ “My software does all this automatically.” ✅ No software can interpret tie forces and notional removal logic—engineering judgement is required. ciria c577

Ronan Point was a wake-up call. CIRIA C577 is the answer. Whether you’re designing a car park, a hospital, or a mixed-use tower, this guide gives you the practical steps to prevent the unthinkable. If you design buildings, manage risk, or construct

❌ “Robustness means designing for a bomb blast.” ✅ No—it means preventing disproportionate collapse, which is usually achieved with simple tying. CIRIA C577 is the answer

Published in 2005 (with updates and related guidance since), CIRIA C577 – Robustness of structures provides a comprehensive methodology for designing and assessing structural robustness. It bridges the gap between the high-level principles of Eurocodes (BS EN 1991-1-7) and real-world construction practice.

From this tragedy came modern robustness requirements. And in the UK, one document stands above the rest for practical guidance: .
