Sažetak
Increase in traffic intensity and speed requires more complex analysis of structures than it was case before ; today it is necessary to consider dynamic behaviour of structures that has been induced by loads moving over a structure. The simplest case of a moving load (dynamic) analysis is the case of a simple beam over which a concentrated load is moving, that is represented with a 4th order partial differential equation. P.D.E. for moving load has been solved numerically with many benefits over closed solution (various boundary conditions, introduction of damping and discrete elements like springs and dashpots, additional supports and many more). Average acceleration method has been employed since direct use of finite differences had shown as being practically unusable. Numerical and ana-lytical solutions have been compared.
