Discomfort Evaluation on Lively Footbridges with Soft-Rubber Pavement
This paper deals with the measurement of the pedestrian perception of the movement of lively footbridges. Several tests on a 80 m single span stress-ribbon footbridge are presented. This footbridge is very slender and has a very low structural damping and several modes under 3 Hz, resulting in sensible vertical movements. Despite of that, general users do not complain too much, probably because its pavement is made of a thick pour-in-place soft-rubber material.
When a pedestrian walks on a flexible pavement, in every step he notices how first the heel, then the toe, sinks and rises, and probably that feeling makes the pedestrian, unconsciously, no to be so demanding regarding the movement of the walkway. To verify this effect, we compare the recordings of three accelerometers installed on the pedestrian when he walks on four different scenarios. Two of the accelerometers are located on one of the pedestrian’s shoes (one at the heel and the other one at the toe) and the third is placed on his hip (all of then in the right side of the body).
The walking scenarios are: rigid and thick soft pavement on solid soil and thin and thick soft pavement on the footbridge walkway. Comparing the acceleration levels in these four scenarios, some conclusions are reached.
