The present paper is concerned with the numerical FEM analysis of dynamic response a simply-supported Euler-Bernoulli elastic beam resting on spatially homogeneous nonlinear cubic Winkler foundation subjected to concentrated moving load. load moves at constant velocity along beam, displaying harmonic-varying magnitude in time, defined terms mean value, amplitude and frequency oscillation. Parametric analyses are performed investigate influence parameters so-called critical velocities,...
A comprehensive rational methodology for the structural assessment of existing bridges is presented and specifically applied to a historic reinforced concrete arch bridge.The based on use non-destructive testing tools model updating procedures involves: (a) preliminary documented research on-site geometric surveys (aimed at collecting information "as built'' geometry); (b) ambient vibration performed by using grid conventional high-sensitivity accelerometers, aimed investigating vertical...
Abstract The present work outlines an original numerical modelization approach for Moving Load (ML) beam problems, by a dedicated object-oriented C++ parallel computing FEM implementation, with the purposes of performing efficient analyses resolving complete dynamic response beams under effect high-velocity ML. Alongside, main framing state-of-the-art reviews are attempted, on principal involved issues of: ML context and physical description, modelization, implementation. Running example...
As a main background practical context of the present numerical investigation, appropriate description track vibrations induced by high-speed trains looks crucial in contemporary railway engineering. The paper is concerned with modelization transient dynamic response simply-supported Euler-Bernoulli beam resting on homogeneous space Winkler elastic foundation, under action transverse concentrated load harmonic-varying magnitude, moving at constant velocity along beam. Two types constitutive...
The structural dynamics analysis of one-dimensional elements (strings, beams) on continuous elastic support under high-velocity moving load is the main subject present doctoral dissertation. Two types mechanical systems have been considered, a finite and an infinite extension. Through ad hoc formulations autonomous implementations, physical dynamic response characteristics taut string/beam-foundation are revealed by virtue analytical numerical approaches, both in linear nonlinear regimes....
