Structural Robustness and Disproportionate Collapse in Buildings


This course aims to equip practising engineers to undertake the full structural design of a building, including designing a robust building to avoid disproportionate collapse.

The course covers designing buildings of Class 1 – 2B and alterations/change of use of existing buildings, and touches on Class 3 buildings.

It is based on the IStructE book ‘Practical guide to structural robustness and disproportionate collapse in buildings’.

Learning outcomes

By the end of the course, you should be able to:

  • Describe the layout and structure of a robust building and explain what makes a building vulnerable
  • Summarise which Legislation is relevant to Disproportionate Collapse and identify key clauses
  • Classify buildings into their types, with respect to building use and size
  • Outline different approaches for achieving robustness
  • Determine a strategy for robustness compliance for buildings of different material types, use and size
  • Analyse an existing building that is being altered or extended and develop an outline scheme for robustness using guidance from London District Surveyors
  • Describe class 3 buildings and discuss an approach to achieving a robust building
