The mountain landscape fits well with slender timber structures. Among them timber bridges are becoming very popular, and the designers are extending the span toward the hundred meters threshold. For a long pedestrian timber bridge in the Italian Alps, the authors had the chance to acquire measurements of the structural response which were collected for periods of few days and repeated in different seasonal weather conditions. A previously developed elaboration of the collected data leads to the validation of a numerical model. In this paper, the numerical model is used to investigate the dynamic response of the structural system which, according to the current structural code, can be ignored along the design process.

Abstract
The mountain landscape fits well with slender timber structures. Among them timber bridges are becoming very popular, and the designers are extending the span toward the hundred meters threshold. For a long pedestrian timber bridge in the Italian Alps, the authors had the chance to acquire measurements of the structural response which were collected for periods of few days and repeated in different seasonal weather conditions. A previously developed elaboration of the collected data leads to the validation of a numerical model. In this paper, the numerical model is used to investigate the dynamic response of the structural system which, according to the current structural code, can be ignored along the design process.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
