At over 828m high, the Burj Khalifa is the tallest building in the world, creating concerns for wind stress and wind vortexes pulling the building from side to side as it has to withstand gusts of over 240 km/h.
Improvements made to the Burj Khalifa
softened edges: deflects the wind and prevents vortices
oriented: relative to prevailing wind direction
1970s - people experienced motion sickness and over 5000 glass panels blew out in moderate winds
Now - no reported issues but still slowly sways 2 metres at the top
