Roof sections of the Sydney Opera House (sh.itjust.works)
The original design of the Sydney opera house featured roof sections with unique curves. This caused two major problems: (1) the structural analysis was very difficult, and (2) it made construction more expensive since they could not reuse construction details among the roof sections. Eventually the engineers realized they could...
