The U.S. Bank Tower features a jagged, glass-paneled crown that breaks the flat skyline of downtown Los Angeles. When it opened in nineteen eighty-nine, its seventy-three stories made it the tallest building west of the Mississippi River. The developer, Robert Maguire, faced intense pressure to limit height due to strict earthquake building codes, but he convinced engineers that a steel-braced frame could withstand the motion. A giant tuned mass damper sits near the top, swaying to counteract the persistent winds pushing against the tower.
