An Evaluating Method for Serving Performance of Pedestrian Bridge―Take Langfang as an Example

Pedestrian bridge becomes more and more popular in cities nowadays, so corresponding evaluation must be made to prove whether it can perform, as well as design requirements or meet the new service performance at present. A comprehensive evaluation method of service performance for the pedestrian bridge is raised by statistic method of gray clustering and other fundamental work, such as vibration experiment, traffic statistics and bridge investigation. The results of service performance of pedestrian bridge in Langfang and satisfaction survey of the bridges are identical by using this method. At the same time, this scientific and objective method can collect a large number of project data for urban planning, bridge design or regular repairs of the bridge.
