EARTHQUAKE

RESISTANT

STRUCTURES A CASE

STUDY

TAIPEI 101

Taiwan's former king of skyscrapers needed

some large-scale engineering to withstand the

country's frequent earthquakes and typhoons

not to mention sitting near a huge fault line. The

solution came in the form of a 730-ton ball of

steel which hangs inside it like a gigantic

pendulum to counteract any swaying. Known asa tuned mass damper, the ball rests inside a

sling made of steel cables and has its own shock

absorbers. That should help ensure Taipei 101

can stand proud for a long while to come, even if

it lost its crown as world's tallest building to the

Burj Khalifa in Dubai in 2010.
