One Rincon Hill tower

location: San Francisco, California, USA
force range: 5340kN
max. length: 5.5 - 6m
The 64-story One Rincon Hill tower in San Francisco was the first structure in which BRB elements were used in the outrigger system. The diagonals which connect the outer steel columns and the concrete core are located between levels 26 to 32 and levels 51 to 55. Total of 16 BRB elements are used in the structure. With the support of Performance-Based Design, dimensions of structural elements could be decreased, therefore smaller columns were used and perimeter beams were eliminated. The latter one has significantly increased the real estate value as floor-to-floor glass fašade was applied.
