Seismic deflection of tall towers
Seismic deflection of tall towers
(OP)
I have a tall tower and seismic controls. Someone wanted to know what the maximum deflection was. As it turns out, the software I use gives me the wind deflection but not the seismic deflection. I'm sure it's due to the seismic calc being complicated. But I was wondering if there was someway to get an approximation of the deflection?





RE: Seismic deflection of tall towers
Deflection of towers is a concern from a process perspective as the liquid sloshing around on the trays can cause the distillation to not work as intended. Most folks, however, agree that a 1 minute seismic event over the life of the vessel will not substantially impact product quality.
Wind events can be far more frequent and so deflection is a bit more commonly a concern.
I'd ask why seismic deflection is an issue... See if you get a process argument or a P-Delta argument.
