The Structural Post-Mortem: When Human Error Meets Technical Failure

Key Insights

The Structural Post-Mortem often result from multiple interacting failures
Human factors are as important as technical design
Safety standards evolve from catastrophic events
Counter-intuitive design decisions can lead to disaster
Ethical considerations are crucial in engineering
