Steady-state vibrations of a beam structure under moving horizontal force-analytical approach [PDF]

Archives of Civil Engineering
The following paper presents a dynamic analysis of a railway superstructure subjected to horizontal moving loads. The superstructure including the substructure was modelled with two infinitely long beams connected by an elastic layer. The structure rests

Damage Identification Method of Beam Structure Based on Modal Curvature Utility Information Entropy

, 2020
Generally, the damage of the structure will lead to the discontinuity of the local mode shape, which can be well reflected by the modal curvature of the structure, and the local information entropy of the beam structure will also change with the ...
