Imperfection reduction factor
WitrynaThe influence of imperfection was also examined by adopting the elastic imperfection reduction factor, α for meridional compression as specified in the ECCS (2008) recommendation into the perfect shells buckling load (GNMA). The shells buckling loads were later discovered to be conservative.
