Buckling Behavior of Corrugated Steel Pipe under External Uniform Pressure

摘要: There are two basic concepts about concerning the buckling analysis of a buried pipe. One concept considers soil around pipe asn elastic continuum mediaum. The other holds that is sup ported by an spring, which replaces effects surrounding (the Winkler model). Theise based on plane analysis, without considering corrugation effect and length effect. This paper thus presents parametric study using Finite Element Method (FEM) for Winker model proposes strength formula after examining 3D effect, thatwhichhelp in estimating critical such CSP
