SWFC

Global financial services giant Wells Fargo opened its Shanghai branch office in the SWFC on March 21. Founded in 1852, Wells Fargo is a diversified financial services company providing banking, insurance, investment, mortgage, and consumer and commercial finance through more than 10,000 branches, 12,000 ATMs and the Internet network across North America and the world. It is headquartered in San Francisco.

On March 26, the SWFC switched off its lights in support of Earth Hour, a global initiative organized by the World Wide Fund for Nature. The event has been held annually around the world since 2007 to raise awareness of the need to take action on climate change.

A new function added to the uplights of the Hang Seng Bank Tower is a weather forecast for the following day. Gold means sunny, white means cloudy and dark blue spells rain. The clever new illumination, which is both aesthetically pleasing and environmentally considerate, was created by renowned firm Motoko Ishii Lighting Design.

● Structural engineering
The SWFC's Dual Lateral Force system combines an exterior mega structure of composite perimeter columns with a service core constructed using SRC tubes. The structural design was supervised by the world eminent American structural engineering firm, Leslie E. Robertson and Associates, RLLP (LERA).

● Building structure
The office tower features a distinctive diagonal-braced frame with exterior and core walls, with the tower's weight distributed on a mat slab. The building is additionally supported by 2,200 steel tubing bearing piles inserted up to 78 meters into the ground.

● Building sway controlled by tuned mass dampers
Two vibration control systems consisting of tuned mass dampers (TMDs) and a 150-ton counterweight are installed on the 90th floor to reduce building sway and control vibration caused by high winds.
