Seismic retrofits are usually invisible. Michael Maltzan's design for the Hammer Museum's new store takes a different approach, using retrofits as a visible reminder of the Big One that awaits. Diagonal cylinders erupt from display tables to connect to the building's support columns. Developed for NASA in the 1960s, the cylinders are filled with a syrupy silicone fluid that dampens the support columns' vibrations. The damping devices have lately come into widespread architectural use, where they not only mitigate earthquakes but the bending of skyscrapers in high winds and the swaying of suspension bridges.
