Shear deformable dynamic stiffness elements for a free vibration analysis of composite plate assemblies - Part I: Theory
(Elsevier Ltd, 2017)
A procedure for developing the dynamic stiffness matrix of a completely free laminated composite plate based on the first-order (FSDT) and higher-order shear deformation theory (HSDT) is presented. The proposed method ...
Free vibration analysis of spatial Bernoulli–Euler and Rayleigh curved beams using isogeometric approach
(Elsevier Inc., 2019)
This paper deals with the linear free vibration analysis of Bernoulli–Euler and Rayleigh curved beams using isogeometric approach. The geometry of the beam as well as the displacement field are defined using the NURBS basis ...
An improved analysis of free torsional vibration of axially loaded thin-walled beams with point-symmetric open cross-section
(Elsevier Inc., 2016)
The objective of the paper is to analyze the influence of bimoment induced by constant axial loads on the free motion of thin-walled beams with point-symmetric open cross-section. For various boundary conditions, a closed-form ...
Research of long-term behaviour of non-prestressed precast concrete beams made continuous
(Elsevier BV, 2014)
Despite the extensive analytical and numerical research carried out in the last two decades on the long-term behaviour of continuous concrete beams composed of precast units, only limited number of experimental data is ...
Bridge flutter derivatives based on computed, validated pressure fields
(Elsevier, 2012)
This paper presents the results of numerical investigations of bridge aeroelasticity. In particular static
coefficients and instationary flutter derivatives for a symmetric bridge deck section using the Unsteady
Reynol ...
Free vibration study of sandwich plates using a family of novel shear deformable dynamic stiffness elements: limitations and comparison with the finite element solutions
(Elsevier Ltd, 2016)
In this paper, the dynamic stiffness matrix of a completely free rectangular multi-layer plate element based on Reddy's higher-order shear deformation theory is derived. The reduction of the proposed model to the first-order ...
Generalized plasticity model for inelastic RCFT column response
(Elsevier Ltd, 2016)
This paper presents a nonlinear 3d concentrated plasticity beam column element for the analysis of RCFT columns. The element consists of a linear elastic component with a plastic hinge at each end whose inelastic response ...
Section Discretization of Fiber Beam-Column Elements for Cyclic Inelastic Response
(Journal of Structural Engineering-Asce, 2012)
The paper presents studies of the effect of the number of material integration points at the monitored sections of fiber beam-column elements on the local response of typical structural cross sections under an extensive ...
Shear deformable dynamic stiffness elements for a free vibration analysis of composite plate assemblies - Part II: Numerical examples
(Elsevier Ltd, 2017)
The dynamic stiffness elements based on the HSDT and FSDT (and the corresponding dynamic stiffness matrices of a laminated composite plate) have been implemented into the original MATLAB code, and a variety of numerical ...
Free vibration analysis of stiffened and cracked laminated composite plate assemblies using shear-deformable dynamic stiffness elements
(Elsevier Ltd, 2017)
In the paper, the dynamic stiffness method based on the HSDT and FSDT plate theories is applied to study free vibration characteristics of composite stiffened and cracked plate assemblies. The dynamic stiffness matrices ...
