Vertical Actions on Bridge Structure : Comparison of Earthquake and Vehicle Induced Dynamical Forces

Modern vehicles are characterised by great load and speed so that their dynamical influence in bridge analysis should be taken into account. This paper presents dynamical equation suitable for this purpose. Some comparisons of stresses in various bridges have been performed taking into account dynamical load influence, direct support acceleration and EC8 regulations. It has been shown that in some examples dynamical load influence produces the greatest stresses in bridge structure and should be taken into consideration.
