I design complex and long-span bridges. Twenty years of that work has been on structures certified by analysis because they cannot be proof-loaded — erected through partial configurations that are individually unstable, brought to final geometry stage by stage, and signed under professional liability. Those methods appear to transfer to large space structures. This is where I test that in public, where people who know the field better can correct me.

Correspondence welcome, particularly disagreement with the exhibits and anything the field guide has missed. mkasiak@postsingularity.engineer
