Szukana fraza: [Abstract = "The analysis is carried out in order to evaluate the effect of the following parameters \(i\) the speed of the moving load \(ii\) the span length of the beam \(iii\) two types of vibrating configurations of the beam \(iv\) the load`s length and \(v\) the elastic foundation modulus, on the dynamic behaviour of the non\-uniform beam resting on the variable one\-parameter foundation. Numerical examples which showed that the above parameters have significant effects on the dynamic behaviour of the moving load problem are presented."]
