Abstrait:

This work aims to contribute to the development and characterization of dynamic numerical analysis, as well as to show its relevance in structures of footbridge built with wood Eucalyptus Cytriodora and subject to pedestrian loads. This wood has satisfactory mechanical properties and it is to use for structural purposes. These characteristics are responsible for generating light structures with reduced cross-section. However, in structures such as footbridges, increasing flexibility can lead to serious vibration problems, compromising the user comfort and, in extreme cases, structural safety. In this work, the Piracicaba Suspension Footbridge will be studying numerically using ANSYS 15 ®. The results obtained from the simulations in different scenarios were confronted with normative prescriptions that have specified methods to qualify the structural dynamic performance and show that the studied footbridge can present problems of excessive vibrations in the vertical direction, when analyzed the traffic from one or more pedestrians walking or running on the footbridge.
