Abstract:
In this article, the author presents some analytical results dynamic coefficients of cutting force, stem force and moment in steel truss bridge by loading capacity vehicle causing by numerical method. As a result, dynamic coefficients analysis in scope of the study showed that dynamic coefficient of cutting force,stem force and moment of steel truss bridge corresponds to vehicle speed running across bridge to the majority of the exploitation range is greater than the dynamic force being applied use in the country is 1,25 according to the standard 22TCN-272-05. Consequently, using a dynamic coefficient according to bridge design process also needs to pay more attention. The result revealed that this study is the reference to help the engineers having more information to analyze or design bridge safely and being suitable to exploit in reality
