The reference is :

Mahmoodi, P, Robertson, L.E. et others (1987), "Performance of Viscoelastic Dampers in World Trade Center Towers", Dynamic of Structures, Proceedings of the Sessions at Structural Congress'87, Orlando, FL, Aug. 17-20.

The above reference has a picture of the damper in place during the construction of the Tower. Unfortunately, I can hardly see on my copy.

Thanks for the posting of these figures. I do not wish to seek publicity, only for the truth. Originally, I wrote this article for my group of friends who are alumni from New Zealand in discussing how WTC fails. I do not have a lot of time. It should be very interesting for appropriate engineers to calculate the average temperature of WTC at collapse having the amount of fuel, air mass and all.
Sincerely,
Ngon
