Critical buckling load of pile in liquefied soil

Soil Dynamics and Earthquake Engineering, 2020
Buckling instability has been recently identified as a possible mechanism of pile failure in liquefiable deposits and this failure mechanism is not explicitly mentioned in most design codes. To carry out routine design and checking, it is necessary to reliably estimate the critical buckling load of pile for a given liquefiable site.

Critical Buckling Loads for Tapered Columns

Transactions of the American Society of Civil Engineers, 1962
Formulas and graphs for determination of critical elastic buckling loads of uniformly tapered columns having wide flange section, box section, and other cross-sectional shapes are presented; columns with pinned ends, fixed-free ends, fixed-pinned ends, and fixed ends are considered; critical elastic buckling loads may be obtained directly from graphs ...

Stiffness and critical buckling load of perforated sheeting

Thin-Walled Structures, 2006
Abstract This paper deals with selected foundations of the design of perforated trapezoidal sheeting. Based on numerical analysis, graphs on effective stiffness values for perforated sheeting with different arrays of holes are provided. As an outlook on further research, the calculation of the buckling coefficient for a perforated plate under uniform

Approximate Derivation of Critical Buckling Load

Journal of Architectural Engineering, 2009
This paper proposes an approximate derivation for the critical buckling load of a column, based on the application of a uniformly loaded beam's midspan moment and deflection to the buckled column's rotational equilibrium. The curvature of a pin-ended member, when it buckles under axial load, is similar to the curvature assumed by the same member when ...

Safely Exceeding the "Critical Buckling Load" in Highly Deviated Holes

SPE Offshore Europe, 1989
Abstract The critical buckling load, developed by Dawson and Paslay, is generally accepted as the limiting criteria for pushing tubing into a highly deviated hole. This criteria severely limits the distance coiled tubing can be pushed into a highly deviated hole.

Determination of critical buckling loads with Gröbner bases

Computers & Structures, 1995
Abstract Grobner bases and the related Buchberger algorithm offer an elegant computational environment for the triangularization/solution of systems of few polynomial equations together with modern computer algebra systems. Here this approach is applied to the geometrically nonlinear structural analysis of columns and the critical buckling loads of ...

Critical Buckling Load on Large Spherical Shells

Journal of the Structural Division, 1962
Approximate evaluation for watertanks, hortonspheres, vapor containers, containment vessels for nuclear reactors, and so forth, has been computed, taking into account out-of-roundness and local flattened areas; graphs have been plotted giving critical buckling load as function of maximum radial deviation over average chord to flattened area.

Field Curves for Critical Buckling Loads in Curving Wellbores

IADC/SPE Drilling Conference, 1998
Abstract This paper gives a plotting technique and curves for estimating the axial compressive loads for the onset of sinusoidal buckling in curving wellbores. The analysis and data calculation are based entirely on previous work by others. Only the method of presenting the data is new.

Critical Buckling Loads of some Prismatic Plate Assemblies

1976
Prismatic plate assemblies include closed and open section struts, stiffened panels with open or closed section longitudinal stiffeners and longitudinally stiffened tubes. Recent theoretical advances have made possible the computation of critical buckling loads (or natural frequencies) for such assemblies. The answers obtained are “exact”, in the sense

Calculation of Critical Lateral-Torsional Buckling Loads of Beams Subjected to Arbitrarily Transverse Loads

International Journal of Structural Stability and Dynamics, 2019
This paper presents a novel approach for determining the critical lateral-torsional buckling loads of beams subjected to arbitrarily transverse loads. This new method is developed based on the classical energy method. However, the difference of the present method from the traditional energy methods is the formulation of potential energy of external ...
