This paper presents a detailed finite element analysis of a five-layer unbonded flexible riser. The numerical results are compared analytical solutions for various load cases. In the finite element model all layers are modelled separately with contact interfaces placed between each layer. The finite element model includes the main features of the riser geometry with very little simplifying assumptions made. The numerical model was solved using a fully explicit time-integration scheme implemented in a parallel environment on a 16-processor cluster. The very good agreement found from numerical and analytical comparisons validates the use of our numerical model to provide benchmark solutions against which further detailed investigation will be made.

The building moving has more than 100 years’ history. In the building moving, the design of the underpinning joints is one of the key problems. As to the frame structure, the most widely used method is the double beam underpinning system. Our research group has conduct 16 underpinning joints tests considering the different influential factors to study the mechanical performance of it. This paper first introduces the experiment briefly. And then make finite element analysis on the mechanical behavior of the column underpinning joints using the software ABAQUS as the platform. In the finite element analysis, the solid element is adopted and the master-slave contact surface is used to simulate the interaction between the column and the underpinning beams. The results show that the failure of the moving-beam is ahead of the coupling-beam and the bending-shear failure occurred in the moving-beam. As to the interface between the column and the beam, the lower part of the contact failed and the gaps can be seen. From the analysis results, the contact stress on the column is not uniformly distributed and larger in the upper part of the contact surface which is accord to the test results.

The thermo-mechanical nonlinear vibrations and stability of a hinged-hinged axially moving beam, additionally supported by a nonlinear spring-mass support are examined via two numerical techniques. The system is subjected to a transverse harmonic excitation force as well as a thermal loading. Hamilton's principle is employed to derive the equations of motion; it is discretized into a multi-degree-freedom system by means of the Galerkin method. The steady state resonant response of the system for both cases with and without an internal resonance between the first two modes is examined via the pseudo-arclength continuation technique. In the second method, direct time integration is employed to construct bifurcation diagrams of Poincaré maps of the system.
