[SEAOC] Re: [SEAOC] Steel Bracing Connection

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Hi, Martin
I was responding to the attached comment by Rick Drake trying to start 
a discussion on steel connection design.  I am not sure what section of 
blodgett he was referring to so I pass the response on to Rick unless I 
can find it in my copy.

Hope all is well with everyone at EQE.
