Function
- Specify the dynamic factor to be applied due to the motion of traffic rail loads using the dynamic factor table.
Call
From the main menu, select [Load] tab > [Type : Moving Load] > [Advanced] group > [Railway Dynamic Factor Table by Element Table]
Input
Dynamic Factor Table
The value of dynamic factor for the selected elements can be edited using the Dynamic factor table.
Determinant Length : If Auto is selected,the determinant length (Lphi) needs to be specified by the user.
Quality of track maintenance : The quality of the track can be specified in the table and the program calculates the value of Dynamic factor based on:
Reduced dynamic effect :In the case of arch bridges and concrete bridges of all types with a cover of more than 1,00 m, the value of dynamic factors may be reduced using the equation given below. Check the [ ] for the reduced dynamic effect to be applied.
where h is the height of the cover.
Height Of the cover : Specify the height of the cover for the reduced dynamic effect consideration.
Dynamic Factor : Calculated Dynamic factor value based on the inputs.
