Based on experiments,Stevens showed that the physical quantity of external stimuli is directly proportional to the psychological quantity,which is more realistic than the previous annoyance rate model based on Fechner's law.Therefore,this paper introduces Stevens law,obtains Stevens membership function for discrete and continuous distribution based on statistics and psychophysics,and establishes a new annoyance rate model.In order to verify the accuracy and reliability of the improved pedestrian bridge annoyance rate solution,field tests were carried out on the actual pedestrian bridge.The results show that the Stevens annoyance rate model can describe the uncertainty of subjective response more accurately.The fitting value of the approximate curve is in good agreement with the measured value.The Stevens annoyance rate model can provide new evidence on how to evaluate the comfort of pedestrian vibration of footbridges.
