How to ensure that an unconventional foldable steel box lifted above the audience is safe?
THE CHALLENGE:
Assess structural integrity of a custom structure subjected to complex loadings caused multiple unfolding sequences.
Reference to the Houdini Box performance by Franz Harary: https://www.youtube.com/watch?v=712a6r6adis
THE SOLUTION:
- Inspection and retro-engineering of the structure on-site;
- 3D modelling of the structure based on the specifications and measurements;
- Review of the show performance and identification of the critical events;
- Development of a non-linear complex simulation model to represent the effects of those events on the structure;
- Evaluate structural integrity of the structure based on the simulation results;
- Identify possible fatigue failure sites and provide inspection recommendations;
- Complete report and safety certification.
THE RESULTS:
- Spectators and performers artists security maximised;
- Certification and overall safety report of the show equipment.
