anchor bolts

[Subject Prev][Subject Next][Thread Prev][Thread Next]
thanks to your response to my question, but i am looking for a little more 

i understand the difference in action between the anchor bolt and rebar. i am 
wondering whether one take advantage of an anchor bolt failure cone 
overlapping confined rebar in the top of a column or pilaster to increase the 
allowable tension of an anchor bolt group to something approaching the 
capacity of a single anchor not considering the anchor bolt edge distance or 
group affects. it would seem that a deep cone (say 36" to 48") would engage 
the rebar at the base of the cone and then transfer the force over the 
development length of the rebar.  
light pole anchor bolts often have very deep (48" or more)  embedment in 
concrete pilasters and this seems like part of the reason.

any thoughts?

thanks paul franceschi
