Fatigue Load Spectrum of Highway Bridge Vehicles in Plateau Mountainous Area Based on Wireless Sensing

Table 7

Comparison of damage degree between different vehicles and actual traffic flow.

Vehicle model	Proportion of vehicle	N	Range of equivalent stress	100-year injury tolerance	Contrast percentage
V2	5.32%	514	21.4	0.0783	−25.0%
V3	16.07%	1494	15.03	0.0720	−31.1%
V4	1.13%	110	26	0.0316	−69.7%
V5	13.00%	1338	17.47	0.1052	0.1%
Actual traffic flow	—	2357	14.65	0.1045	—

Proportion of vehicle in the table represents the ratio of the quantity of this vehicle model to actual traffic flow. N and range of equivalent stress are both calculation results under 24 hours. Contrast percentage is the percentage of difference from the damage degree of actual traffic flow.
