Hi,

There are two more important issues that need some discussion in design and construction of tall buildings:

1. Axial Shortening of compression members and how to deal with it during the design, detailing and construction
2. Damping systems that are useful for wind damping, seismic damping and which one are available to use in India

Any thoughts from the current designers of tall buildings as well as contractors would be welcome.

Regards,

Vikas

Dear Er Vikas,

With regard to wind, tuned mass damper as well as sloshing water damper are few of the passive choices and they are very efficient in dissipating energy and control motions. As far as I know, buildings don't have any damper of this type yet in India though in the very near future some buildings may get this.
