Enjoy the cloud lake view at the John Hancock Center in Chicago.

The John Hancock Center in Chicago is the world's first comprehensive building, located in the bustling area of North Michigan Avenue, where high-end apartments, shops, office buildings, hotels, restaurants, and art galleries are gathered. The external steel frame of the building forms a simple body, and the structure floor at the junction of the diagonally distributed steel and the corner column, together with the diagonally distributed steel itself, provides the necessary rigidity for the building. In order to meet the functional organization structure, the cross-section of the cylinder is also the largest where the stress caused by wind pressure is the greatest. The John Hancock Center in Chicago is a historic collaboration between architects and structural engineers, using for the first time a diagonalized outer cylinder structural system developed specifically for this building. With the help of the new structural system, the original plan of two separate buildings was built into an economical and efficient comprehensive functional structure, so that more open space can be provided on the original site.
