Studco's Vortex Framing System Reduces Creaking in Tall Buildings
Studco developed a high-performance framing system to mitigate creaking sound in tall buildings.
Tall buildings, much like tall trees, sway in windy conditions, says Studco Building Systems. This is caused by a phenomenon known as vortex shedding. Vortex shedding occurs when wind runs into a tall building and the wind is "split" into two separate air streams around the building.
This generates areas of low pressure on the opposite side of the building, which creates a suction-effect that causes the building to sway. And when that building sways, it creaks. Some buildings can generate creaking sounds up to 70 decibels (dB). This is louder than a conversation in a restaurant or office, and can be as loud as a running vacuum cleaner. This keeps apartment residents awake at night, and terrifies unsuspecting hotel guests.
