Buried Pipe Modeling With Initial Imperfections

Journal of Pressure Vessel Technology, 2004
A formulation using the finite element method is presented in this paper to analyze stresses and displacements of underground pipelines with initial imperfections. The formulation includes both thermal expansion of the pipeline and internal pressure. The method is based on large deformation beam theory with the finite element formulation based on Euler-

Stayed Column with Initial Imperfection

Journal of the Structural Division, 1982
The effect of an initial out-of-straightness on the buckling strength of a single-crossarm stayed column is investigated. A geometrical study of the stayed column is used to determine the relationship between the applied load, lateral deflection and the tension in the stays.

Critical initial imperfection of structures

International Journal of Solids and Structures, 1990
Abstract A method is introduced for determining the critical initial imperfection of discretized structures that decreases the load-bearing capacity most rapidly. The effects of imperfections on simple critical points, such as limit points of loads and simple bifurcation points, are theoretically investigated based on the idea of the Lyapunov-Schmidt

Random initial imperfections of structures

International Journal of Solids and Structures, 1991
Abstract This paper is a theoretical study on random initial imperfections of structures. The explicit form of probability density function of the load-bearing capacity (critical load) of structures is derived for random initial imperfections based on a decomposition of the space of imperfection vectors into two orthogonal subspaces: the subspace ...
