[TowerTalk] Need some help

[Ruslin Prawira]

Dear sir,

I have designed some telecommunication tower using
Staad.Pro 2004, the design procedures were based on
design by others. I am a structural engineer but have
never got specific knowledge on steel structure design
codes for tower.

I need help to know what formula to check for maximum
sway and twist at top area of the tower. Or maybe
there are some reading materials that I could look up.

Thanks a lot.

Ruslin
