I'm designing a Tower Crane, i'm using SAP2000 and all the elements passed, but i have a problem or a doubt with the deflection, in the top i have obtained aprox. 80 cm, the height of my tower crane is 80 metros, the AISC standards allow a ratio of 1/500, I just want to know if i m ok, or what do i have to do?
I have read in previous forum a ratio of 1/1000 but wher do i get that information? What standard allows it?
Thank you for your help,
