Anchorage to concrete

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Section 1923.2 of the 97 UBC indicates that

"When anchors are embedded in the tension zone of a member the load factors 
in Section 1909.2 shall have a multiplier of 3 if special inspection is not 
provided, or of 2 if it is provided."

I need clarification of what the "tension zone of a member" means.

If a base plate is sitting on a concrete beam directly over a cantilever 
support the anchors would definately be in the member's tension zone.

Does this requirement also apply to a base plate that has a large moment 
that puts some of the anchor bolts into tension (or) a base plate which 
transfers uplift forces to all of the anchor bolts?

Please help clarify what type of situations this applies to.

Thanks in advance
