RE: Steel connection design

[Subject Prev][Subject Next][Thread Prev][Thread Next]
It was also conspicuously absent in the 2000 IBC.  This is standard practice on the west coast but the IBC is not written by west coast engineers alone. 
 
If the lateral force connections [or gravity connections for that matter] are going to be handled by the fabricator without the engineer or record providing typical details, then they probably are not exempt from the practice of engineering in your state and still need to have an engineer's stamp.  If this is not included on your plans or in your specifications then the manufacturer may only be providing unstamped shop drawings which do not meet the practice of engineering requirements in your state.

Subject: Steel connection design

Under the 2003 IBC (i.e. outside of California), what are the code requirements relating to steel connections that are required to be detailed by the engineer of record on the design drawings? 
 
I cannot find anything directly in the 2003 IBC or ASCE 7-02 that is comparable to the UBC requirement that "connections that resist design seismic forces shall be designed and detailed on the drawings".  However, the AISC seismic provisions are required to be followed when R exceeds 3 or in Seismic Design Categories D, E, or F; and the AISC Seismic Provisions require the "configuration, material specifications, and sizes" to be shown for connections that are part of the seismic load resisting systems.  So, it appears that connections must be detailed for those cases. 
 
This would infer that the connection design can be deferred to be by the fabricator for a structure in Seismic Design Categories A, B, and C with R=3 (or lower).  
 
- Just want to confirm my interpretation.
