RE: tilet up wall anchor

[Subject Prev][Subject Next][Thread Prev][Thread Next]
When you read A325, you will notice that it is not a rod specification.  It
is strictly a bolt specification.  A307 is also a bolt specification.  The
A36 specification applies to mild steel rod, and there are several
specifications for high strength steel rods depending on the mechanical
properties required.

I guess I don't know what is being requested.  High strength materials
generally do not have the elongation, nor the ductility of lower strength
carbon steels.  Obviously they do have higher strengths, and when it comes
to cyclic loading the design predicates how you optimize that strength.

hi everyone

is anyone has answer for a plan check correction it .
will be thankful

the plan check engineer wants me to specify the wall tie anchor
to A325 steel rod not A307 first he said the reason is ductility after
that he said is dynamic loading 
any answer
