Generation of IMPACT FACTOR of Bridge Standard Loading
Generation of IMPACT FACTOR of Bridge Standard Loading
(OP)
Hi friends,
I am working on generating a standard bridge loading for our country. I have established standard design vehicles by analysing the traffic axel load data of our country. Now I want to establish a relation for computing IMPACT FACTOR on bridges.
So, can anybody help me by suggesting me the method of calculating IMPACT FACTOR.....?

I = 50/(L+125) where L is equal to the span length under investigation. I is limited to 0.3.
For regions of the span where there is continuity over the supports, the L is the average of the adjacent spans.
This has served us well over the years since the code's inception.
