| Research Abstract |
A calculation method of axle loads was developed. The method uses strain responses of orthotropic steel deck structures when heavy vehicles pass. The method was applied to a vehicles running test with three heavy trucks, the axle weights of which are 207.6kN, 310.1kN and 411.3kN. In total 85 axle passages, the average error was -2.1% and the standard deviation of the errors was 6.7%. For one-week continuous monitoring data in an actual orthotropic steel deck structure, the result showed axle loads over 100kN passed 1,793 times and those over 200kN did 31 times.
