The Petronas Towers are an impressive pair of 88-storey supertall skyscrapers located in Kuala Lumpur, Malaysia. Standing at a height of 451.9 m (1,483 ft), these iconic towers are renowned as the world’s
tallest twin skyscrapers and remained the tallest structures in Malaysia until 2019, when they were overtaken by The Exchange 106. 

The Motioneering team reviewed the design of the Petronas Towers' skybridge which incorporated two
long and slender support legs and t was established that they would be vulnerable to wind-induced vibrations,
known as Vortex-Induced Oscillation (VIO) response. This VIO response could have significantly affected the
strength and stability of the legs.

​

To counteract this, Motioneering implemented a solution to increase the “inherent damping” within the
leg structures. This was achieved by strategically locating Tuned Mass Dampers (TMDs) inside the
centre of each of the skybridge's legs, These Tuned Mass Dampers (TMDs) were carefully designed to
increase the damping effect by a factor of 3, thereby enhancing the structural integrity and resilience
against wind-induced forces.
