Ciria C577 🔥 No Ads

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

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. ciria c577

In 1968, the partial collapse of Ronan Point tower block in London changed structural engineering forever. A minor gas explosion led to a disproportionate collapse—a small failure triggered a chain reaction far larger than its original cause. If you design buildings, manage risk, or construct

❌ “My software does all this automatically.” ✅ No software can interpret tie forces and notional removal logic—engineering judgement is required. Whether you’re designing a car park, a hospital,

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

CIRIA C577: The Essential Guide to Structural Robustness for Builders and Engineers

With the rise of BIM and parametric design, CIRIA’s methodology is increasingly being automated. Some engineering firms now script notional removal checks into their analysis software. However, the —why a building is robust—still comes from the principles in C577.
