The Moody Amphitheater is an outdoor music and performing arts venue located in a transformed park in Austin which serves a dual function as a recreational space and a ticketed concert venue. The amphitheater's focal point is a 20,000sf steel canopy composed of alternating layers of stacked I-beams, arranged in a denser pattern over the stage and feathering out at the edges. The canopy provides shelter to a cast-in-place concrete stage and support facility which houses concession, back-of-house and VIP areas, and is carefully integrated with the park landscape.

The structural scheme developed for the canopy satisfies the high stage loading requirements without reducing its sculptural quality. Fabricated steel trusses are carefully concealed within the “cloud” of over 2,000 individual steel and aluminum members, all of which are supported on impossibly slender rectangular steel columns that also provide stability to the canopy without the use of lateral bracing. The exposed curved concrete walls of the support facility trace the geometry of the site and are carefully detailed in accord with its architectural expression. The framed concrete roof structure has been designed to carry high loading due to the canopy and green roof above, while at the same time incorporating mechanical systems and maximizing floor to ceiling height.
