Stepped Column Critical Buckling Load Estimation

9th International Students Science Congress Proceedings Book
The construction field mainly deals with columns that have two cross-sectional areas, especially in high-height work forms called stepped columns. Standard sections, with varying loads and exact spans, are usually used at different heights to construct the work form. As a result, many accidents happen on construction sites.

Advances in critical buckling load assessment for tubulars inside wellbores

Journal of Petroleum Science and Engineering, 2014
Abstract Prediction of drill strings buckling load has been a challenge to the drilling industry. This work attempts to review most of the research performed in the previous years. First analytical, numerical and experimental researches on buckling in different wellbore geometries such as vertical, inclined, curved and general real world cases are ...

Natural Frequencies and Critical Buckling Loads of Marine Risers

Journal of Offshore Mechanics and Arctic Engineering, 1988
Natural frequencies, mode shapes and critical buckling loads of marine risers simply supported at both ends are given in closed form by using the WKB method. These solutions allow variable cross section, bending rigidity, tension and mass distribution along the riser length.

Experimental Evidence of Erosion of Critical Load in Interactive Buckling

Journal of Structural Engineering, 2013
AbstractThe paper starts with a selective review of some basic contributions related to local-overall buckling mode interactions in thin-walled steel members. Then, the results of an intensive experimental study carried out at the Politehnica University of Timisoara with the purpose of evaluating the erosion of a theoretical bifurcation load in the ...

Critical load and application of core-separated buckling-restrained braces

Journal of Constructional Steel Research, 2015
Abstract A new type of buckling-restrained braces (BRBs), called core-separated buckling-restrained braces (CSBRBs) is presented and investigated in this study. The CSBRBs are composed of two chord members and one or several continuous web plates that connect those members longitudinally.

Critical Buckling Load for Wound Carbon Epoxy Composite Cylinders

1990
The aim of the theoretical and experimental study presented here is to evaluate the critical buckling load of filament wounded composite cylinders under external pressure. The first part discribes the experimental device. The second part deals with the hypothesis of the finite elements study.

Partially embedded piles subjected to critical buckling load—Sensitivity analysis

Computers & Structures, 1996
The first variation of the critical buckling load of a pile partially embedded in a soil due to a change of a design variable is derived. The one-dimensional idealization of the pile in conjunction with the soil represented by the Winkler-type elastic foundation is considered. The effect of the skin friction is neglected. The pile material and the soil

Lower Bounds for Critical Buckling Load Using Matrix Norms

Journal of Engineering Mechanics, 1993
A method is proposed to compute lower bounds for the critical buckling load in problems of matrix structural analysis and in finite-element analysis. The method is based on the fact that the critical buckling load is equal to the reciprocal of the spectral radius of a modified geometric stiffness matrix for the problem.

Predicting the Critical Buckling Load for a Graphite/Epoxy Laminate

Journal of Composites Technology and Research, 1980
The critical buckling load for a slender specimen of an isotropic, homogeneous material can usually be predicted adequately from fundamental strength-of-materials considerations. The extension of this approach to specimens of composite materials can be accomplished formally by using appropriate anisotropic elastic constants in the Euler buckling ...

The calculation of critical buckling loads for externally constrained structures

Communications in Numerical Methods in Engineering, 1999
Summary: A method of identifying the critical load of structures, the buckling shape of which is constrained, is presented based on two novel techniques. The first identifies this critical or limit point buckling value using a linear, complementary algorithm to solve what is shown to be a quadratic programming problem, while the second adopts a ...
