Building Load Combinations
Building Load Combinations
(OP)
I work in the oil and gas area and need to upgrade our specs for pre-engineered metal buildings used for compressor buildings, meter buildings, etc.
If we specify IBC instead of UBC does this code specify the load combinations for design? Or do we need to reference the metal building specs for load combinations?
Also, does the IBC reference ASCE 7 for wind, etc. loads or do we need to add a reference to ASCE 7?
Most of our facilities are out in the middle of nowhere. Hence we could normally specify either IBC or UBC although I do have a statement to the effect of ahereing to all local codes. I have noticed on recent quotes that the building vendors prefer IBC.
Seems that our management decided to reduce the scope of our IHC subscribtion as a cost saving measure which prompts this question as I cannot look up the answers. Recent lay offs have also reduced our structural engineering capabilities in this area such that I do not get a warm and fuzzy feeling from the guys left on the above issues.

The way I approach writting specifications is to write a text portion which would be applicable to any project and then add a data sheet which is site and project specific.
My initial plan was to write the text of the spec with IBC as the primary code and then state that any local codes would apply. I think this gives me an out in case the local county has any funny requirements or wants UBC and makes the vendor responsible for the research.
The above is based on my assumption that IBC is sufficient. My post is partly to determine if I have to supplement it with design load combination requirements or the basis of determining wind, snow, seismic, etc. loads.
In today's super competitive environment the goal is to work with the building vendor's standard design as opposed to creating requirements for 100% custom design.
