Architecture Design of Chicago Spire – Skyscraper Residential Building by Santiago Calatrava

The Chicago Spire will be completion at 2010 and will be new icon of Chicago city. This amazing residential tower designed by Spanish based architects Santiago Calatrava principal design team members including Perkins & Will (Architect of Record), Thornton Tomasetti (Structural Engineers) and Cosentini (Mechanical/Electrical Engineers). If completed, at 2,000 feet (610 m) and with 150 floors, it will be among the world’s tallest buildings and freestanding structures.
Standing at 2,000 feet (610 m), the Chicago Spire would further transform the always-changing Chicago skyline, the Chicago Spire will be the world’s tallest exclusively residential building and the tallest building in the western world. Plans for the tower include 1,193 condominiums with each of the building’s 150 stories rotating 2.4 degrees from the one below for a total 360 degree rotation. For supplemental structural support, each floor would be surrounded by cantilevered corners and four concave sides. Similar to the Willis Tower (formerly Sears Tower) and John Hancock Center observation decks, the Chicago Spire will house a community room at the top floor offering residents a view of four states.[46][47][48] The soaring four story lobby of the skyscraper will have translucent glass walls and be framed by arching, steel reinforced concrete vaults. The building has been labeled as a giant “drill bit” by the public and others in the media have likened it to a “tall twisting tree” and a “blade of grass”.
The curved design, similar to that of Calatrava’s Turning Torso in Malmö, Sweden, may provide two major benefits to the structure of the building. First, curved designs have a tendency of adding to the strength of a structure. A similar principle has been applied in the past with curved stadium roofs. In addition to structural support, the curved face of the exterior will minimize wind forces. In rectangular buildings, a fluid wind flow puts pressure on the windward face of the building; while air moves around it, a suction is applied to the leeward face. This often causes a sway in tall buildings which can be counteracted, at least partially, by stiffening the structure or by using a dynamic wind damper. Although the curved design of the Chicago Spire will not completely negate wind forces, a tapering concrete core and twelve shear walls emanating from it are installed to counteract these forces instead.

Additionally, the Chicago Spire will incorporate world-class sustainable engineering practices to meet Leadership in Energy and Environmental Design Gold recognition. Sustainable features include recycled rainwater, river water used for cooling, ornithologically-sensitive glass to protect migratory birds, intelligent building and management systems, waste storage and recycling management, and monitored outdoor air delivery.
