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.
