how to calculate embedment length for cf
 

how to calculate embedment length for cft ?
i would like to know if there are some guide lines to calculate the embedment length of a cft (concrete filled tube), i don't know if the formulas for anchor bolts works fine.
what is the purpose of the tube?
hi structuraleit ,
the tube works as column of a strucutre with fabric at top, and the uplift force comes from the wind analysis. we are talking of structures' dimensions as 20'x40'x 16' ht
