chicopee, I dont know why you thought this 'whole thing is a hoax'.
I saw the video and responded immediately that we cant stop this vibration induced by applying push force on the centre/joint of horizontal and diagonal bracings, simply because the towers are not designed for this force.
But...
We normally do not consider the effect of these 'distribution bars' in flexure resistance of one way slabs. They just help in controlling cracking that's why they are also called as temperature and shrinkage reinforcement.
Thanks Folks
I just printed this page and showed the responses of you guys to my boss and everybody here was laughing. :)
That video was made by a guy who always points problems in everyone's work.
Anyhow, I modeled the towers on SAP2000 and applied 100 kg force at the same point where that...
Hi Friends, I have a strange problem to discuss...
I work for National Grid. Few days back, I got a video in which a person was applying force on the lowermost diaphragm/horizontal bracing of the latticed steel tower. He was applying force manually (which probably wouldn't be more than 50 kgf)...
I also think that only local deflection shall be checked. If the beam in consideration is fixed ended, it already has transferred its effect to the supporting beam. Now you are only concerned with the deflection of the 'supporting beam', instead of the 'supported beam'.
A similar analogy of...
