Walter Jack l Public Art Memorial in Australia

This stunning public art memorial by Walter Jack to John Curtin in Australia uses 3.5m high brass plates that are only 30mm thick and they sway gently on windy days.

Their extreme slenderness ratio, the sharp change in cross section along with the presence of high wind loads, made the design of these brass panels located in Perth a challenging structural engineering problem that’s hidden behind the apparent simplicity of this piece of art.
