540 Lack of lateral stability in steel frame

This concerns three similar buildings. The roof of Building No 1 was a concrete-composite deck supported on lattice trusses and it collapsed whilst carrying a moderate imposed load. The report relates to the findings on one of the other similar buildings designated Building No 2.

576 Worker trapped in excavation

An operative was trapped within an excavation which collapsed and he received serious injuries. Ground water was found in the excavation but not noted as a hazard. The trench was not supported and the risk of an unsupported trench collapsing was not well enough recognised either before work was undertaken, or whilst it was in progress. Collapse was due to the instability of the trench sides.

July 2016 CROSS Newsletter No 43 published 

We depend on individuals and firms participating by sending reports of their experiences and concerns in confidence to Structural-Safety. The names of reporters are never revealed and only the technical aspects that could help structural engineers are published. 

If you have an experience that could be useful to others please contribute by sending a report to www.structural-safety.org/confidential-reporting/.


Structural-Safety works with the professions, industry and government on safety matters concerned with the design, construction and use of building and civil engineering structures. It:

  • collects confidential data on the concerns of structural and civil engineers and others
  • provides comments in relation to these concerns
  • maintains a data base of reports and publications
  • collects data from public sources on failures, collapses and relevant incidents
  • considers whether unacceptable risk exists, or might arise in the future
  • promotes a positive attitude to learning from experience
  • influences change to improve structural safety
  • collects data on weather related damage to structures.

Structural-Safety combines CROSS and SCOSS. Click here for more details.
