| Summary: |
| The paper presents an analysis of the influence of vehicle speed movement
along bridge on dynamic amplification factor for the case of simply supported, continuous
and clamped beam structural system. The analysis was conducted analytically and
numerically. Theoretical expressions was developed for the case of movement a
concentrated force over the bridge over simply supported beam structural system, while
other cases were analyzed numerically. Two cases, movement of concentrated force and
system of concentrated forces were considered. The comparative results for the most
unfavorable case, with the valid domestic and foreign regulations, compared and
presented. The results showed that it is a more unfavorable case when vehicles are moving
at higher speeds on short-span bridges, as well as that one concentrated force produces
greater dynamic effects than a system of concentrated forces, as well as the simply
supported beam system is the most sensitive on dynamic loads respect to other structural
systems. |
