Abstract: Centrust Tower in Miami, Fla., is a $95 million, 37 story, 600,000 sq ft tower rising from one side of a block-square 11 story parking garage. Columns on the curved side of the triangular tower trace an arc through the garage, which is owned by the city and has been in use since 1982. Axis of the privately owned tower is 45 degrees off the rectangular parking axis, and the elevator cores are completely separate. Tower columns resist all wide as well as gravity loads. Unusual eccentric transfer brackets were used at two setbacks rather than conventional transfer girders. The brackets, laterally braced by interior and exterior wall panels, reach between floors that act as in-plane diaphragms. In each pair of floors, one is subjected to compression while the other is in tension.
