RE: L-shaped A490 Anchor Bolts

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The only problem I have had with the F 1554 is the Table 3.  There is an 
obvious typo in the Gr 105 in the reduction of area.  It has a -45 
...really?    The only other problem is the Gr 55 which has a reduction of 
area that puts it in conflict with the ACI 318 Appendix D for the 
definition of "ductile".  To be ductile per ACI, the material needs a ROA 
of 30%.  When you read actual mill certs for a Gr 55, a value of 30% or 
greater is very common.  I am in the process if trying to get this changed 
in the F1554 spec.
