The top 25 stories of this 29-story tower cantilever over the main structural columns below via story-deep trusses. Employing an innovative lateral-force resisting system consisting of shear-link ductile steel frames and a cross-braced structural core, LeMessurier was able to maximize the strength and stiffness of the building while minimizing the impact the framing would have on the architectural programming.
