TL;DR: Laterally loaded piles are analyzed using the Fourier FEM as mentioned in this paper, where the analysis is performed for piles embedded in single-layer elastic soil with constant and linearly varying modulus and in two-layer linear elastic soil, with constant modulus within each layer.
Abstract: Laterally loaded piles are analyzed using the Fourier FEM. The analysis is performed for piles embedded in single-layer elastic soil with constant and linearly varying modulus and in two-layer elastic soil with constant modulus within each layer. The pile responses were observed to be functions of the relative stiffness of pile and soil, and of the pile slenderness ratio. Based on the analysis, equations describing pile head deflection, rotation, and maximum bending moment are proposed for flexible long piles and stubby rigid piles. These design equations are developed after plotting the pile responses as functions of pile-soil stiffness ratio and pile slenderness ratio. These plots can also be used as design charts. Design examples illustrating the use of the analysis are provided.

TL;DR: In this article, static experimental tests on four half-scale models of steel and concrete composite girders with different shear connectors such as studs and Perfo-Bond Strips (PBLs) under hogging moments are cautiously conducted in order to investigate the reduction of flexural stiffness and the inelastic behaviour after cracking.

TL;DR: In this paper, a multilayer shell model is presented for the pure bending buckling of an individual multi-walled carbon nanotube, in which the effect of van der Waals forces between adjacent two tubes is taken into account.
Abstract: This paper reports the results of an investigation on bending stability of an individual multiwalled carbon nanotube. Based on the point of view of continuum modeling, a multilayer shell model is presented for the pure bending buckling of an individual multiwalled carbon nanotube, in which the effect of van der Waals forces between adjacent two tubes is taken into account. Here, the critical bending moment and the bending buckling mode for three types of multiwalled carbon nanotubes with different layer numbers and ratios of radius to thickness are calculated. Results carried out show that the bending buckling mode corresponding the critical bending moment is unique, which is obviously different from the purely axial compression buckling of an individual multiwalled carbon nanotube. It is also seen from numerical examples that the distribution of the critical bending strain for each tube of multiwalled carbon nanotubes under bending is dependent on the radius-to-thickness ratio and the layer number of the multiwalled carbon nanotubes. The new features and interesting numerical results in the present work are helpful for the application and the design of nanostructures in which multiwalled carbon nanotubes act as basic elements.

TL;DR: In this article, a mixed finite element model for the nonlinear bending analysis of laminated composite plates is presented, which is obtained using a mixed variational formulation of the first-order shear deformation theory of plates in which displacements and bending moments are treated as independent fields.
Abstract: A mixed finite element model for the nonlinear bending analysis of laminated composite plates is presented. The finite element model is obtained using a mixed variational formulation of the first-order shear deformation theory of plates in which displacements and bending moments are treated as independent fields. A p-type Lagrangian basis is used to approximate the nodal degrees of freedom that consist of three displacements, two rotations, and three moment resultants. The geometric nonlinearity in the sense of the von Karman is included in the plate theory. The mixed plate element developed herein is employed in the linear and nonlinear bending analysis of a variety of layered composite rectangular plates. The effects of transverse shear deformation, material anisotropy, and bending-stretching coupling on deflections and stresses are investigated. The predictive capability of the present model is demonstrated by comparison with analytical, experimental, and numerical solutions available in the literature...
