Project

Stochastic vibration of beam structures due to moving random loads and wind actions. (GC13-34405J)

The wind load combined with the moving load acting upon the bridges or their load-bearing parts is a serious problem in the light of ever growing requirements; longer spans, lighter structures and higher resistance...

Project

Characteristics of the random excitation of mechanical systems (IAA2071602)

Recent results of stochastic mechanic render possible the direct solution to the response of deformable systems to random loadings like wind, industrial seismicity or displacements and to describe them as non-stationar processes

Project

Intensive vibration of structures under moving loads and degradation of their properties (IAA2071103)

The mechanical systems subjected to loads that are moving at high speeds (e.g. bridges, rails, pavements) become in resonance at certain critical speeds. The intensive and many times repeated stresses result in damages of structures...
