Finite Element Instability Analysis of the Steel Joist of Continuous Composite Beams with Flexible Shear Connectors
Composite steel/concrete beams may buckle in hogging bending regions. As the top flange of I-beam in that arrangement is restricted from any translational deformation and twist, the web will distort during buckling presenting a phenomenon often described as restricted distortional buckling. There are limited studies available in the literature of restricted distortional buckling of composite st...
متن کاملNew Method for Large Deflection Analysis of an Elliptic Plate Weakened by an Eccentric Circular Hole
The bending analysis of moderately thick elliptic plates weakened by an eccentric circular hole has been investigated in this article. The nonlinear governing equations have been presented by considering the von-Karman assumptions and the first-order shear deformation theory in cylindrical coordinates system. Semi-analytical polynomial method (SAPM) which had been presented by the author before...
متن کاملResponse Determination of a Beam with Moderately Large Deflection Under Transverse Dynamic Load Using First Order Shear Deformation Theory
In the presented paper, the governing equations of a vibratory beam with moderately large deflection are derived using the first order shear deformation theory. The beam is homogenous, isotropic and it is subjected to the dynamic transverse and axial loads. The kinematic of the problem is according to the Von-Karman strain-displacement relations and the Hook's law is used as the constitutive eq...
متن کاملOn the Hybrid Stress Finite Element Model for Incremental Analysis of Large Deflection Problems
Abatmct-An extension of the hybrid stress finite element model, originally suggested for linear small displacement problems by Pian, to the large deflection problem is presented. An incremental approach and the concepts of initial stress are employed. A procedure to check the equilibrium in the reference state, prior to the addition of a further load increment, is included. An example and a dis...
متن کاملNonlinear Dynamics Analysis of FGM Shell Structures with a Higher Order Shear Strain Enhanced Solid-Shell Element
In this paper, non-linear dynamics analysis of functionally graded material (FGM) shell structures is investigated using the higher order solid-shell element based on the Enhanced Assumed Strain (EAS). With this element, a quadratic distribution of the shear stress through the thickness is considered in an enhancing part. Material properties of the shell structure are varied continuously in the...
