Abstract

Nowadays, modern bridge constructions are very sensitive to the dynamic load due to the use of light materials with high load capacity and low absorption. In case of the footbridges, it is an associated with the occurrence of vibration resulting from force effects caused by pedestrian movement. There is an excessive vibration of structure which is a problem of the serviceability limit state rather than the problem of the ultimate limit state. This type of load can cause the resonance of the structure so it is necessary to prevent this problem, for example by installing the vibration damper. The subject of this article is an analysis of a wooden footbridge in Pribor in the Czech Republic which is monitored for the effects of load models caused by persons. The article describes experimental measurement focused on this problem and the subsequent proposal for possible measures.
