An elegant residential hotel tower located at the south edge of Vancouver's business district, the elliptical 45 storey One Wall Centre is one of Vancouver's tallest buildings. Completing the third phase of Wall Center development, the structure comprises a 34 storey hotel and a 29 storey tower for residential use, with a curvilinear low-rise podium containing commercial and retail space, and a central landscaped plaza connecting the slender hotel tower to the existing buildings. Designed to become one of the city's signature buildings, the translucent, elliptical tower is a bold and exciting architectural statement requiring innovative engineering.
Despite its impressive height, One Wall Center was designed to have a minimal impact on Vancouver's skyline. The resulting 7:1 height-to-width ratio created unique structural engineering challenges requiring innovative solutions that would satisfy wind and seismic design requirements. To meet seismic load and wind-resistance challenges, the tower uses an unusual outrigger system consisting of four floors of six-foot-deep concrete beams that connect the central elevator and stair cores to exterior columns. The system resists the forces of wind and earthquakes by spreading the axial load of the building out to the columns. With this 'tuned liquid column damper' and two rooftop 50,000 gallon water tanks - intended to counter any lateral movements in the tower - the structure is designed to withstand a once-in-a-100-year windstorm. The rooftop water can also supplement the tower's sprinkler system if a fire gets out of control.
