NEW YORK – The second meeting for the CTBUH research project entitled “A Study on the Damping Technologies Available for Tall Buildings: Comfort and Safety” was held at the Grand Hyatt in New York on October 26, 2015 as part of the CTBUH 2015 International Conference. Nearly 30 industry professionals and academic experts were in attendance, along with representatives from Bouygues Construction and CTBUH. The project, funded by Bouygues Construction, aims to summarize the collective knowledge accrued over the last few decades regarding the construction and design of structures with damping systems and to trace future possibilities in the field.
Attendees engaged in the meeting
The meeting started with a general overview of the first research steps conducted since the project launched in May 2015. Subsequently, the group undertook a lively discussion on how the report’s Table of Contents should be restructured to maximize the clarity and comprehensibility of the research. They also carefully considered how the report’s different authors should specifically contribute to each section, and initiated a major reorganization of the chapter plan. The salient outcomes of the meeting were a revised Table of Contents and the subsequent process to be followed.

As part of the research effort, three site visits were conducted on October 29 by Bouygues representatives and CTBUH researchers. The first visit was at 601 Lexington Avenue in New York. The tour, led by Patrick Cooper (Boston Properties) and Craig Blanchet (LeMessurier), provided a detailed overview of the building’s tuned mass damper. The second visit at 250 West 55th Street, led by Boston Properties and David Farnsworth (Arup), explored the tower’s damped outrigger, which is equipped with seven viscous dampers. Finally, at One57, 157 W 57th Street, the group examined the tuned liquid damper at the top of the tower with guidance from Extell Development Company and Cynthia Lu (WSP).
