It has been observed from previous large earthquakes that weakening the structural foundation can reduce damage of structure itself by allowing a rocking motion to release seismic energy, and this design philosophy is gradually applied new constructions. In paper, simplified model process rigid block proposed, equation derived, parameter analysis carried out. was found height–width ratio dampin...

In this paper, the dynamic response of resonating nano-beams is investigated using a strain gradient elasticity theory. A nonlinear model is obtained based on the Galerkin decomposition method to find the dynamic response of the investigated beam around its statically deflected position. The mid-plane stretching, axial residual stress and nonlinear interaction due to the electrostatic force on ...

This paper is concerned with the analysis of bending edge waves travelling in a thick Kirchhoff-type piezoelectric film resting on Winkler–Fuss foundation. The electromechanical coupling accounted for defining flexural rigidities to embrace and dielectric material constants. Dynamics solved analytically demonstrated numerically by assuming harmonic wave propagation. It observed that an increase...

As a new type of retaining structure, lattice beams with tie-back anchor cables have been increasingly used in slope reinforcement and achieved improved prevention effects. However, the simplified load distribution method (SLDM) at node, which is theoretical basis internal force analysis for beams, not perfect present. An alternative (NLDM) node based on beam was therefore introduced this paper...

Transverse vibration of two axially moving beams connected by a Winkler elastic foundation is analyzed analytically. The system is a model of paper and paper-cloth (wire-screen) used in paper making. The two beams are tensioned, translating axially with a common constant velocity, simply supported at their ends, and of different materials and geometry. Due to the effect of translation, the dyna...

In the present study, the analysis of nonlinear vibration for a simply-supported flexible beam with a constant velocity carrying a moving mass is studied. The amplitude of vibration assumed high and its deformation rate is assumed slow. Due to the high amplitude of vibrations, stretching is created in mid-plane, resulting in, the nonlinear strain-displacement relations is obtained, Thus, Nonlin...

In this study, the torsional stability analysis is presented for thin cylindrical with the functionally graded (FG) middle layer resting on the Winker elastic foundation. The mechanical properties of functionally graded material (FGM) are assumed to be graded in the thickness direction according to a simple power law and exponential distributions in terms of volume fractions of the constituents...

In the present work, effect of von Karman geometric nonlinearity on the vibration characteristics of a Y-shaped single walled carbon nanotube (Y-SWCNT) conveying viscose fluid is investigated based on Euler Bernoulli beam (EBB) model. The Y-SWCNT is also subjected to a longitudinal magnetic field which produces Lorentz force in transverse direction. In order to consider the small scale effects,...
