Abstract:
A corrugated structural metal plate curved from a generally flat configuration to include an arcuate curvature in its longitudinal direction, comprising:a plurality of longitudinally extending corrugations defined by alternating crests and valleys; each of said crests being in tension when said structural plate is curved about an axis transverse to its longitudinal axis and having a substantially flat first segment in transverse cross section extending longitudinally along said crest; and each of said valleys being in compression when said structural plate is curved about the axis transverse to its longitudinal axis and having a substantially flat second segment in transverse cross section extending longitudinally along said valley; wherein each of said substantially flat second segments has a cross-sectional width that is less than a cross-sectional width of each of said substantially flat first segments.
