High-speed train-induced ground motion and interaction with structures
(Elsevier, 2007)
A general numerical model for the analysis of soil motion due to high-speed train passage and effects on nearby surface and underground structures is presented in this paper. Soil, ballast and structures are represented ...

Modal identification of a pedestrian bridge by output-only analysis
(Society for Experimental Mechanics (SEM), 2005)
The modal parameters (natural frequencies, mode shapes and damping ratios) describe the dynamic properties of a mechanical system. The classical modal analysis, based on Frequency Response Function, require measurements ...

Analysis of ground motion due to moving surface loads induced by high-speed trains
(Elsevier, 2007-11)
A three-dimensional time domain boundary element (BE) approach for the analysis of soil vibrations induced by high-speed moving loads is presented in this paper. An attenuation law is included in the formulation. By doing ...

Computing stress singularities in transversely isotropic multimaterial corners by means of explicit expressions of the orthonormalized Stroh-eigenvectors
(Elsevier, 2009-01)
Composite materials reinforced by unidirectional long fibers behave macroscopically as homogeneous transversely isotropic linear elastic materials. A general, accurate and computationally efficient procedure for the ...
