As an example, I've seen photos of steel buildings with the roof and wall panels blown off. Without a careful study it is difficult to tell from a photo if the engineer left off a safety factor or if the contractor left off a brace or if the owner left the OHGD open or if the structure experienced loads exceeding the design event.

It's almost impossible to comment without knowing a LOT more details about the testing. Really, one can't comment without reading a full report.
Buddy Showalter, Tom Skaggs, and I could likely fill your e-mail inboxes to overflowing with a discussion of boundary conditions, wall/panel configurations, and their effects on test results. 8-)
