Abstract
This paper deals with a human response exposed to vibration concerning bridge serviceability. Bridge serviceability test is conducted both on a existing pedestrian bridge with the fundamental frequency of about 2.1 Hz for vertical vibration and on a existing pedestrian suspension bridge with the center span of 62.4 m for lateral vibration. Based on these full scale measurements for both immovable standing position and footfall (walking), it was confirmed that pedestrians in immovable standing position might be more sensitive compared with footfall (walking). Bridge serviceability-acceleration characteristic for human response to the lateral vibration is also proposed from a bridge design viewpoint.
