The new system, which minimises the standard ‘wobble’ in high-rise buildings, employs the same technology used to strengthen the
‘The swaying of tall buildings is a perennial issue caused by high winds and even earthquakes,’ said Rob Smith, associate, Arup. ‘We’ve worked to find an economical and effective solution to the problem and are delighted that the new technology developed by Arup is being put into practice in a high rise building for the first time today.’
The usual methods employed to strengthen buildings are to reinforce it with significant extra structure or to install tuned mass dampers. According to Arup, both methods are expensive, make the building stiffer and heavier, and consume space.
The Arup solution works by inserting viscous dampers into the St. Francis Shangri-La Place building to act as energy absorbers and damp out vibrations. This is said to be a low cost solution that is also more sustainable as it uses less material, and leaves more space inside the building.
