When failure is clearly due to yielding, the load obtained will be reduced in the ratio of the specified yield strength to the measured yield strength. Should failure be due to rupture at a weld or bolted section, the ultimate strength must be used. In cases where instability occurs in the elastic range, deemed to be when > 1.5, no adjustment is needed, but should it occur in the elastic-plastic range, then the test value will be reduced by the factor
where
Fy = specified yield strength Fy’ = measured yield strength
No adjustment is made if the properties are lower than those specified, and the test is passed.
