Review Questions

• Explain how the tuned mass damper (TMD) in Taipei 101 helps to mitigate the effects of forced oscillations.
  • The tuned mass damper in Taipei 101 is a massive 660-ton pendulum suspended from the top of the building. This pendulum is designed to counteract the movement of the building caused by wind or seismic activity, effectively reducing the amplitude of the forced oscillations. The pendulum's natural frequency is tuned to match the natural frequency of the building, allowing it to absorb and dissipate the energy of the oscillations, preventing the building from reaching a state of resonance and minimizing the risk of structural damage.
• Describe how the unique design features of Taipei 101, such as its pagoda-like structure and tapered shape, help to reduce the impact of resonance.
  • The structural engineers of Taipei 101 utilized the principles of structural dynamics to optimize the building's design and minimize the effects of resonance. The pagoda-like structure and tapered shape of the building alter its natural frequency, making it less susceptible to resonance with external forces like wind or earthquakes. By adjusting the building's natural frequency, the designers were able to ensure that it did not match the frequency of the expected dynamic loads, preventing the amplification of vibrations that can occur during resonance. This innovative approach to the building's design, combined with the use of the tuned mass damper, has made Taipei 101 a highly effective and resilient structure in the face of challenging environmental conditions.
