Real Geometrical Imperfection of Bow-String Arches—Measurement and Global Analysis

open access: yesApplied Sciences (Switzerland), 2020
In order to analyse the buckling behaviour of existing bow-string arch bridges, it is necessary to deal with the imperfections that influence the global stability of their superstructures. Direct quantification of the material imperfections represents an

Most adverse geometrical imperfections of steel spherical shells

open access: yesBudownictwo i Architektura, 2014
Steel, spherical shells subjected to an external pressure are exposed to the loss of stability and such a phenomenon determines the global resistance of such shells.

Post-Buckling Behaviour of Steel Structures with Different Types of Imperfections

open access: yesApplied Sciences, 2022
In this paper, the stability of steel members with a complex initial geometrical imperfection pattern are analysed. This issue is extremely important in the case of slender structures, characterised by multiple close critical loads and modal interactions,

The Ultimate Strength of Fully Transparent Pressure-Resistant Spherical Cabins

open access: yesApplied Sciences, 2023
The fully transparent cabin used in a manned submersible is typically made of the viscoelastic material polymethyl methacrylate (PMMA). The pressure-bearing capacity of a PMMA-manned cabin was investigated considering the effects of initial geometrical ...

Ring Stiffened Cylindrical Shell Structures: State-of-the-Art Review

open access: yesApplied Sciences, 2022
The cylindrical shell is a widely used structure in engineering practice, and its main form of failure is instability due to buckling. As a classical problem in the field of mechanics, the stability of cylindrical shells has been studied extensively ...
