Free vibration analysis of Timoshenko beams has been presented. Discrete singular
convolution method is used for numerical solution of equation of motion of Timoshenko …

A crack in a steel structure will cause a local change in its stiffness. The change in stiffness
will lead to a change in buckling loads and a discontinuity in the associated buckling modes …

In this work a considerable number of papers regarding the cracked beam like structures in
the literature are cited. A new and general governing differential equation for eigenvalue …

Due to both wave and wind fluctuations, the steel foundations of offshore wind turbines are
highly submitted to fatigue. To date, current methods of fatigue design proposed in the …

The actual challenge for requalification of existing offshore structures through a rational
process of reassessment indicates the importance of employing a response surface …
