Highway vehicle-bridge coupled vibrations
WebIn practical situations, it is challenging to obtain specific single vehicle responses promptly on large highway bridges in operation. As shown in Fig. 1, for a typical cable-stayed bridge (the investigated bridge in case study herein; five days of monitoring data are considered), if the minimum number of overlapped vehicle responses per minute is counted, single …
