Performance Based Design of Viscoelastic Coupling Dampers in Mass Timber Buildings

Viscoelastic Coupling Dampers (VCDs) have been developed over the past 15 years at the University of Toronto and by Kinetica for use in multi-storey buildings constructed with conventional construction techniques (steel and concrete). It has been shown the VCDs improve the wind and seismic performance of these buildings, leading to safer, higher performing and more resilient structures.
There has been a boom of mass timber construction due to the inherent sustainability, modularity and speed of construction using mass timber.

Resilience of modern skyscrapers subject to natural hazards - Year two

The structural performance of skyscrapers subjected to natural hazards such as strong winds and earthquakes has significant effects on the resilience of a city because of the recent boom in the construction of skyscrapers around the world. However, resilience is currently not explicitly considered in the design of tall buildings. Studies show that modern tall buildings can suffer significant damage due to natural hazards and they might need to be closed for up to 2–3 years for repair. This has serious socio-economic repercussions.

Recent years have witnessed a boom in the construction of modern high-rise buildings in megacities around the world. It is important to design a high-rise building that can effectively withstand both wind and earthquake loads. Nonetheless, in current practice, the design of highrise buildings for wind and earthquakes is done independently. Hence, there is an urgent need to develop a set of integrated design guidelines for both wind and earthquake loads.

Recent years have witnessed a boom in the construction of modern high-rise buildings in megacities around the world. Since many of these megacities are also located in seismically active regions, it is important to design a high-rise building that can effectively withstand both wind and earthquake loads. Nonetheless, in current practice, the design of high-rise buildings for wind and earthquakes is done independently. Hence, there is an urgent need to develop a set of integrated design guidelines for both wind and earthquake loads.

Viscoelastic Coupling Dampers for Enhanced Dynamic Performance of a High-Rise in Toronto

The biggest challenge faced by structural engineers in the design of high-rise structures is to control the dynamic responses of these structures due to wind and earthquake vibrations. While the traditional techniques of stiffening and adding vibration absorbers can mitigate the vibrational response to a degree, they also increase the construction cost and result in a loss of leasable space in the building structure.
