The ground floor would have "normal" cosmetic damage. Lateral loads are taken by six 2-ft-dia interior columns-all isolated. Each concrete-filled steel-pipe column has a 1-ft-tall triple-pendulum ...

The isolated columns take loads to a grid of post-tensioned-concrete grade beams, set up as the yielding mechanism in the lateral system. If movement exceeds 2 ft in any direction, the isolators lock ...
