Plan

SOM

Y-shaped floor plan is ideal for residential program • Maximizes window perimeter to floor plate area• Is inherently stable

Buttressed core• Three wings arranged around central core• Each wing supports other two

Setbacks occur at each wing in a spiraling pattern • Reduces vortex shedding by changing building

shape 24 times • Modular system = no transfers

All high performance concrete construction• Reinforced concrete core walls linked to exterior

columns• More rigid structure = less motion

Wind Tunnel Testing at RWDI

• Application• unusual geometry• significant motion-induced

forces

• Output• accelerations• overall base overturning

moment• estimated equivalent lateral

forces• aerodynamic damping

Aeroelastic Test

SOM

Acceleration (mg) Usage

Movement of the Tower

• Buildings move under wind or seismic loading

• Computer models are used to calculate this movement

• Acceleration Summary:

Return Period = 10 yearsDamping Ratio = 1.5%
