| Abstract: |
The current German guideline for reassessment of existing road bridges (Nachrechnungsrichtlinie) allows for constraining measures for road traffic in order to reduce the load impact on bridge structures. However, quantification of this reduction is specified only for selected cases in the guideline. This paper presents results from analysis of the effect of different constraining measures for unidirectional road traffic, such as no passing of motor trucks, minimum inter- vehicular distance regulation, and modification of traffic routing, on the resulting structural demands for selected highway bridges. The results are compared to the reference case of normal, unconstrained traffic to demonstrate the effectivity of different constraining measures. Findings from this analysis can serve as base for calibration of modified load models for bridge reassessment when enforcing the respective constraining measures for road traffic. |
