In this paper in situ dynamic test results on a long span timber footbridge are reported. As a result of evident flexibility of the structure not taken into account for during the design phase, the test engineer required a dynamic test just after footbridge concluding, with the aim to get realistic values of the main dynamic performances so as to compare them with numerical models.

Abstract
In this paper in situ dynamic test results on a long span timber footbridge are reported. As a result of evident flexibility of the structure not taken into account for during the design phase, the test engineer required a dynamic test just after footbridge concluding, with the aim to get realistic values of the main dynamic performances so as to compare them with numerical models. By means of a refined numerical model, it was so possible to analyse the structural performance under many environmental loads, namely wind, live load and earthquake.File in questo prodotto:
