METHOD FOR DESIGNING CORRUGATED STEEL SHEET, AND CORRUGATED STEEL SHEET PIPE

WIPO Patent Application WO/2013/002094

A1

Provided is a method that is for designing a corrugated steel sheet and that is characterized by, when designing the corrugated shape of a corrugated steel sheet that configures a corrugated steel sheet pipe of tube diameter D comprising a corrugated steel sheet having corrugations having a wave depth of H, setting the wave depth (H) with respect to the tube diameter (D) in a manner so that, with the presumption that the corrugated steel sheet pipe will incur uniform external pressure at the outer surface, the annular buckling pressure (pcr) when the corrugated steel sheet pipe buckles and the yielding pressure (py) when the corrugated steel sheet pipe yields are equivalent.
