What is the foundation of the Flatiron Building?

详细说明

The Flatiron Building's foundation is a deep foundation, which extends several feet below the building's basement level. The foundation is composed of several interconnected footings and piers, which are designed to transfer the weight of the building to the underlying soil and rock. The foundation is also designed to resist settlement and movement, and is anchored to the building's structural system through a system of deep foundations and footings. The building's foundation has been reinforced and upgraded over the years, and has been designed to meet modern seismic and wind load standards.
