Working @ LHAS - Slinky Stair

Here's another project I have been working on recently. This stair hangs from those large roof beams and may be totally isolated from the surrounding structure. We're trying to minimize crossbracing so we have been investigating the structure's mode shapes and frequencies. Also, the roof will be clad with glass so we are also keeping an eye on dead and live load deflections. This thing would swing like a Slinky in a California earthquake, but here in DK, where the ground never moves, structures like this are actually feasible.
