RE: Confused about Welding Procedures

[Subject Prev][Subject Next][Thread Prev][Thread Next]

The structural engineer is supposed to define the overall testing program,
defining what connections get tested and how that testing is to take place.
Minimum elements of the testing program are included in Sect 1703.  Keep in
mind this is just for fully restrained connections in seismic zones 3 and 4
(the kind that failed in Northridge).

You might want to take a look at FEMA 267.

The welding procedure is just for an individual welded joint, and just
describes the procedure to weld a particular joint.
