Hi, since we're already on this topic. Could you kindly share with us how do you plan to cope with the vibrations from the rotating blades & further vibrations/swinging caused by the wind (lateral force)...and perhaps would you look into the area of resonance vibration/swinging which destroyed...

Correct me if I'm wrong...but I don't think the steel member will be in direct contact with the ground. It would most likely has some 10-20ft deep reinforced concrete piles, and sitting on top of those piles are the pile-caps using engineering grade grouting. The steel structure will normally...

Hi, I wouldn't worry about sun hitting the steel frame. Steel has a very high critical temperature point. I would suggest you to look at the material manufacturer's data sheet/mechanical properties. I believe the critical temperature is somewhere in there. Assume it is around 400deg C, there is...
