Furthermore, in order to emphasize the applicability and the effectiveness of the derived dynamic stiffness, dynamic analysis of the simple beam-cable structure is performed. It was found that the inclined cable always presents the hybrid modes and that the dynamic stiffness in this paper represents...
The free field responses of the layered saturated poroelastic ground are obtained by the stiffness matrix method. The tunnel is assumed to be an infinitely long beam resting on a viscoelastic foundation. The soil skeleton displacements of the saturated ground are converted to dynamic loads imposed ...
The elasticity modulus and mass density of the functionally graded beam are assumed to vary exponentially along its thickness direction. Local stiffness matrix model-based finite element analysis (FEA) is conducted to determine the bending stiffness and tensile stiffness of the section with a crack, ...
Exponential matrixImpedance functionsInclined pilesKinematic interaction analysisSoil-structure interactionThis paper presents an analytical model, based on the beam-on-dynamic Winkler foundation approach, for the evaluation of impedances and kinematic response of single inclined piles. The pile is modelled ...
The protruded part is treated as a cantilever supported at its end by an equivalent spring group representing the part of fiber inside the matrix. The relationship between bridging stress and crack opening width is then calculated by the consideration of axial loading acting on the beam as well ...
In this study, a theoretical model incorporating an inclined pile group and a saturated half-space was established, wherein the pile and saturated soil were described by the E-B beam and Biot poroelasticity theories, respectively. The pile and soil were coupled through the receptance matrix, ...

as a beam on an elastic foundation with variable stiffness and the possibility of spalling, Leung and Li [18] developed a micro-mechanical model to analyze the coupled fiber bending-matrix spalling mechanism and to determine crack bridging stress in random fiber-reinforced brittle matrix composites....
To more accurately describe the motion characteristics of the TLP in the marine environment, the tension leg was simplified as a massless spring model, a lumped mass model or a nonlinear beam model. The 6-DoF stiffness matrix and the coupled nonlinear motion equation and boundary conditions of ...
This phenomenon resembles a “leverage effect” or the distribution pressure on an upper cantilever beam, where the structural internal force peaks at the stratigraphic boundary. The transfer of shear forces intensifies the vertical load at the ends of the inverted arch, further increasing the ...
