Did you model the full length of the culvert ( 2.4 m ) or are you modeling a 1 m length for the analysis ? If you calculated the load considering the length of 2.4 m and then for the analysis you are analyzing a 1m length only, then you should divide the load by 2.4 and apply it to the top of your model. The load may be distributed among the top nodes based on the width of influence of each node as mentioned in my last post.

Thanks Sye for the reply. I have calculated the lateral force in kN. Normaly in 2 D analysis , we apply the nodal load at the top node in the structure,but, as I am dealing with the lay length of 2.4m, I am unsure that, I should divide the nodal load by 2.4m and multiply by 1m.

If I am understanding the question correctly, you have calculated the total load and would like to find out how much to apply at each node. So dividing the total load by the length would give you the load per unit length. You can then multiply that by the influence width of each node to find out how much to apply at each node.
