Impact Factor in Railway Steel Bridge
Impact factor is an important factor to consider when designing railway steel bridges. It accounts for the dynamic effects of a moving train on the bridge structure. The impact factor is generally expressed as a percentage of the live load.
Loaded Length of Span
The loaded length of span is the length of the bridge that is subjected to the live load of the train. It is usually measured from center to center of the adjacent spans.
Impact Factor Calculation
The impact factor is calculated using the following formula:
Impact Factor = (Length of Live Load / Loaded Length of Span) - 1
For a railway steel bridge carrying a single track with a loaded length of span of 6 meters, the impact factor is taken as between 0.5 and 1.0.
Explanation
The impact factor is a measure of the dynamic effects of a moving train on the bridge structure. It takes into account the fact that the live load of the train is not static, but rather dynamic in nature. The impact factor is calculated by comparing the length of the live load to the loaded length of the span.
In the case of a railway steel bridge carrying a single track with a loaded length of span of 6 meters, the impact factor is taken as between 0.5 and 1.0. This means that the dynamic effects of the moving train are significant and must be accounted for in the design of the bridge.
Conclusion
In conclusion, the impact factor is an important factor to consider when designing railway steel bridges. It accounts for the dynamic effects of a moving train on the bridge structure. The impact factor is calculated by comparing the length of the live load to the loaded length of the span. For a railway steel bridge carrying a single track with a loaded length of span of 6 meters, the impact factor is taken as between 0.5 and 1.0.
