RE: ASCE Wind Speed Criteria

[Subject Prev][Subject Next][Thread Prev][Thread Next]
What you say is true for structural engineers serving
the petrochem industry. But I have come across several
mechanical, process engineers etc, particularly in the
field offices, who use uniform wind pressure (handed
down to them from their peers, perhaps) in designing
structures.
