STAAD.ProV8i (SELECTseries 5)is a suite ofproprietary computer programs ofBentley
Systems, Inc.. Althoughevery effort has beenmade toensure the correctness ofthese programs,
Bentley Systems, Inc. will not accept responsibility for any mistake, error, or misrepresentation
inor as a result ofthe usage ofthese programs.
NotesonComparisons
Ineachverificationproblem, a table is usedtosummarize the numerical outputs from
STAAD.Prowitha reference or handcalculations. Adifference columnpresents the percent
deviationfromthe reference, whena significant difference exists.
The deviationis takenas the reference value minus the value determinedby STAAD.Pro, divided
by the reference value toexpress inpercent ofthe reference.
Inthis context, "significant"is take as larger thana 1% (one percent)difference. Whena
difference between0.5% and1% exists, thenthe difference is simply listedas "<1%". Otherwise,
the difference is listedas "none".
This level ofsignificance is intendedtoreflect that small differences inrounding or calculation
methods donot present a realistic difference inthe calculatedresult.
