The Mensa bridge in Hannover, Germany is a footbridge crossing the street Schneiderberg and connects the universites' canteen and the park. The dataset contains measurments of the vertical and the horizontal accererations of the bridge deck under ambient excitation (e.g. wind and pedestrians) and impuls excitation. The impuls excitations have been realized using a modal hammer. The impuls has been applied at six diffent positions, three times in vertical direction (DSV) and three times in horizontal direction (DSH) near the sensor that is indicated in the filename.
