Practical Advanced Design Considering Random Distribution of Initial Geometric Imperfections
Advances in Structural Engineering, 2011Current advanced analysis and design of steel frames, allows for the most unfavorable combination of initial imperfections. In fact, however, the initial geometric imperfections and their combinations are all random distributions. Recognising this situation, the sway installation tolerances and bow imperfections of both columns and beams are all ...

Influence of initial geometric imperfections on vibrations of thin circular cylindrical shells
Computers & Structures, 1983Abstract The influence of initial geometric imperfections (out-of-roundness) on vibrations of a right circular cylindrical shell is investigated on the basis on non-linear large deformation shell theory. Both free and forced motions (due to base excitation caused by seismic effects) are treated.

Study on Buckling of an H-Shaped Steel Member with Initial Geometric Imperfection
Applied Mechanics and Materials, 2012Based on Ježek method of computing the elastic-plastic buckling of the member under the axial compressive load and the bending moment, considering the initial imperfection, the analytical expressions of calculating the ultimate load of buckling about the neutral axis with the maximum moment of inertia for an H-shaped member are derived.

The results from studies into the vibrations and dynamic stability of thin elastic shells with initial geometric imperfections are analyzed. The corresponding dynamic problems are solved in both linear and nonlinear formulations. The influence of initial axisymmetric and nonaxisymmetric deflections on natural, forced, parametrically excited, and self ...

Effects of Initial Geometric Imperfection on Stability of Single-Layer Reticulated Shell
Advanced Materials Research, 2011The stability of reticulated shell is a key issue for single-layer reticulated shell. In the paper, a single-layer arch-supported shell structure was analyzed by finite element software MIDAS. The eigenvalue buckling analysis and the geometric nonlinear overall stability analysis with initial imperfection of the model which carried two different load ...

Collapse of semi-rigidly jointed reticulated domes with initial geometric imperfections
Journal of Constructional Steel Research, 1998Abstract Buckling collapse and its analytical method of steel reticulated domes with semi-rigid ball joints are discussed, on the basis of a nonlinear elastic–plastic hinge analysis formulated for three-dimensional beam-columns with elastic perfectly plastic hinges located at both ends and the mid-span for each member.

Strain, 1988
Several analytical methods are outlined to deal with the title problem when the vessel is free of external constraints. In essence these correspond to the Haigh equation, which provides a nonlinear relationship between the induced circumferential stress and the applied internal pressure.
