Measurement on the Influence Lines of Bridge Responses Corresponding with Moving-Load Position

Abstract:

With more and more precise calculation and analysis to the bridge, and its carrying capacity assessment and repair reinforcement universal attention, it is necessary to acquire the influence line of bridge responses corresponding with moving-load position. A method is presented to obtain the influence line by experiment. A laser rangefinder with large range is added to original test instruments. The moving load position parameter can be looked on as displacement after the signal conversion, which can be synchronously collected together with the response signal. The inverse function principle is introduced to process the data. The examples indicate that the present approach can accurately measure the influence line.
