Influence of Slenderness Ratio on Buckling Behavior of Reinforced Concrete Columns: A Finite Element Analysis

open access: yesAdvances in Materials Science and Engineering, Volume 2025, Issue 1, 2025.
Reinforced concrete columns (RCCs) are critical load‐bearing elements in structural systems, where stability is often governed by buckling, particularly in slender members subjected to axial compression. While extensive studies exist on column buckling, there remains a need for integrated approaches that couple analytical formulations with advanced ...

A mixed hexahedral solid‐shell finite element with self‐equilibrated isostatic assumed stresses for geometrically nonlinear problems

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 125, Issue 24, 30 December 2024.
Abstract Mixed Finite Elements (FEs) with assumed stresses and displacements provide many advantages in analysing shell structures. They ensure good results for coarse meshes and provide an accurate representation of the stress field. The shell FEs within the family designated by the acronym Mixed Isostatic Self‐equilibrated Stresses (MISS) have ...

Dynamic Post-Buckling Behavior

open access: yesTransactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2017
Geometric non-linear theory has been used to describe the post-buckling behavior of slender web. Hamilton’s principle in increments has been used. Examples of dynamic post-bucking behavior of slender web loaded in compression are presented.

Vibration and flutter analysis of piezoelectric plates in an electrothermal field using higher order theories

open access: yesEngineering Reports, Volume 6, Issue 12, December 2024.
Non‐local elasticity based on high‐order shear theories is used to model the structure. The aerodynamic flow on the plate surface is modeled using the linear piston theory. The vibration and dynamic stability of a thick rectangular plate are investigated by hamilton principle.
