KRON4 - One Rincon Hill Earthquake

Earthquake Preparedness in San Francisco's Tallest Building

Overview of the Earthquake Impact

• The recent quake caused significant structural sway, affecting buildings up to 160 miles away from Tokyo.

• Maureen Kelly reports from the site of the tallest residential tower under construction in San Francisco, emphasizing its importance for earthquake preparedness.

Features of the One Rincon Hill Condo Project

• The One Rincon Hill condo project stands at 641 feet, making it the tallest residential tower in San Francisco. Its height is advantageous during seismic events.

• The building incorporates advanced seismic technology that has not been previously utilized in the country, enhancing its resilience against earthquakes.

Seismic Technology Explained

• The main structural system is compared to a downhill skier: stout columns act as ski poles while a concrete core represents the skier's body. Braces function like arms, transferring loads effectively during an earthquake.

• A unique feature includes a water tank on the roof capable of holding 100,000 gallons. This water counteracts building sway by moving in opposition to it, creating friction and reducing acceleration felt by residents.
