- Map code requirements to Load Cases. Ensure all sub-cases are covered (Operations may need to be broken up into with/without vacuum, process piping pressure, etc.) Cases that are trivial should be listed, even if no analysis is completed.
- In other words, please list all loading conditions / combinations considered for all load cases (including design load parameters and associated factors, seismic load magnitude(s) and direction(s), etc).
- Please clarify the acceptance criteria? What are the point(s) overall structural instability is considered to occur? Are any service criteria considered?
- Are the loading conditions / combinations the same for plastic collapse and local failure (i.e. all load steps)?
- What load step is used for the analyzing the bolted connections? What load step is used in the hand calculations?
- Review implementation of the Importance Factor 1.5. ASCE 7 section 13.3 applies this as a direct multiple to SDS. I have not looked at the BPVC implementation of seismic loads in a long time, but I think something equivalent is applicable.
- Review any potential effects of deflection to operating requirements. We saw significant analysis of loads and stresses, but minimal review of deflection. Generally, I expect the BCC to be aligned without load, and it would be good to ensure alignment will be maintained under operating conditions. (Rob provided some review of the 1.3GHz from 2016 that may have impacts.)
- Consider conservative approach to weld efficiency factors, in particular for structural welds.
