Structural Integrity and Disproportionate Collapse

Structural Engineering 🏛️ ICE ⏱ 3 CPD Hours Member

About this CPD Resource

How to design structures to resist disproportionate collapse under accidental loading in line with Approved Document A and Eurocode requirements for robustness.

Structural robustness — the ability of a structure to withstand accidental events without disproportionate collapse — is a fundamental requirement of building regulations. Approved Document A and Eurocode 1 set out requirements for robustness that vary by building type and consequence class. Understanding and correctly applying these requirements is an important structural engineering competency.

Learning Outcomes

  • Understand robustness requirements under Approved Document A
  • Apply key element and tying force design approaches
  • Assess the risk of progressive collapse in different building types
  • Design structures to withstand accidental loading scenarios

Why This CPD Matters

Structural engineering sits at the heart of safe, efficient and sustainable construction. The structural engineer's fundamental duty — ensuring that buildings and infrastructure are safe for their intended use — has been reinforced and scrutinised by the Building Safety Act 2022, which places new competency requirements on those working on higher-risk buildings. The Institution of Structural Engineers and the Institution of Civil Engineers both require their members to demonstrate ongoing competency development through CPD, and structural design practice is constantly evolving through updates to Eurocode standards, new materials and construction methods, and the growing importance of embodied carbon in structural design decisions.

This CPD from Institution of Civil Engineers addresses structural engineering knowledge that is directly applicable to professional practice. Whether you are working towards or maintaining Chartered Membership of IStructE or ICE, or seeking to develop your technical knowledge in a specific area of structural practice, structured CPD from recognised providers contributes to the evidence of competency that professional bodies require.

Key Topics and Industry Context

Structural engineering encompasses the analysis, design and verification of load-bearing elements and systems in buildings and infrastructure. The Eurocodes — the European structural design standards adopted across the UK — provide the primary framework for structural design and are periodically updated, requiring practitioners to maintain their knowledge of current requirements. Materials science and construction methods are evolving, with developments in engineered timber, high-strength concrete, glass-fibre reinforced polymer (GFRP) reinforcement and structural steel driving new approaches to design. The assessment and strengthening of existing structures is a growing area of practice as the industry shifts towards retrofit and adaptation of the existing building stock.

This resource from Institution of Civil Engineers provides structured learning in an aspect of structural engineering practice that is relevant to professionals at all career stages, from graduates developing their foundational knowledge to experienced engineers updating their understanding of current standards and practice.

How This Fits Your CPD Requirements

IStructE requires all Chartered Members (MIStructE) and Fellows (FIStructE) to complete a minimum of 30 hours of CPD per year, of which at least 16 hours should be structured activities with defined learning objectives. ICE does not set a fixed annual minimum but requires members to maintain a CPD record demonstrating ongoing development. The Engineering Council's UK Standard for Professional Engineering Competence (UK-SPEC) requires all professionally registered engineers to demonstrate commitment to continuing competency development. Structural engineering CPD from recognised providers such as this one contributes directly to meeting these requirements.

What is a consequence class?
Approved Document A assigns buildings to Consequence Classes (CC1-CC3) based on their size, use and occupancy. Higher consequence classes require more detailed consideration of accidental actions.
What is the key element approach?
For CC3 buildings, structural engineers must identify key elements whose removal would cause disproportionate collapse. These must be designed to withstand an accidental design pressure of 34 kN/m2.
When is a risk assessment required?
A systematic risk assessment is required for all CC3 buildings — those above 15 storeys or with large undivided floor areas.
